Living under the heel of a despotic Evil Overlord and his Empire is no picnic even for those blind to their tyranny. No surprise then that La Résistance does everything it can to make his reign difficult. Luckily, what La Résistance lacks in numbers it makes up for with loyal grassroots support from the oppressed people because The Revolution Will Not Be Vilified. No matter how good the tyrant's publicity, only the foolish believe him and all the people that matter help La Résistance.
Except, of course, for Les Collaborateurs. Why fight against the Evil Overlord when helping him can give you money, power, and revenge against all those pretty popular kids that just joined La Résistance? Les Collaborateurs can act as The Mole, spreading and gathering intelligence, as saboteurs within the resistance by undermining their own efforts, or as an agent of distrust and discord to break apart The Alliance. Les Collaborateurs are only too happy to sell out their countrymen like animals to the slaughter, even if signs point to the villain having a penchant for killingcollaborators.
Usually they're unctuously Smug Snakes or a low grade Magnificent Bastard. And no, these guys will not end up Becoming the Mask or doing a Heel-Face Turn — they've tasted power and found it sweet. You can, however, expect them to think that their utter betrayal will somehow make The Chick insanely attracted to them (Love Makes You Evil meets Go-Go Enslavement). Thankfully, the cosmic sense of justice ensures that all collaborators meet with particularly grisly Karmic Deaths.
In Real Life, it's often a murkier picture. Ordinary, upstanding citizens across Europe "collaborated" to greater and lesser extents with Nazi occupation, for instance, and many of them were just trying to make the best of a bad situation. Others were maligned for simply fraternizing with the invaders to any extent. After the war, it was common practice in France, as well as probably elsewhere, to shave off the hair of women who have had intimate relations with German soldiers, for whatever reason. And while there were many executions legal and otherwise post-D-Day (the exact number is disputed), people in positions of authority who had collaborated were often given amnesty or left unpunished. (François Darlan for example switched sides without consequence before he was assassinated, possibly by the SOE).
If a member of Les Collaborateurs is given a position of power or influence over the conquered people, then he becomes The Quisling.
See also Transhuman Treachery and Dying Like Animals. Compare The Remnant. This trope is the villain opposite of La Résistance, and the government they collaborate with is The Empire. When they are on the battlefield (willingly or not), they are Battle Thralls.
In Mai-Otome, Tomoe joins forces with Nagi when he conquers Windbloom and holds the students of Garderobe hostage, hoping to use her newfound powers and freedom to achieve her own personal goal of getting Shizuru to fall in love with her.
In One Piece, the White Berets agree to work for the usurper "God" Eneru in the hopes that they could protect the people of Skypiea by doing so. This proves futile when Eneru revealed that he had planned to destroy Skypiea and travel to the Endless Vearth, but Conis understands what the White Berets were trying to do.
Long before that, Nami agreed to join Arlong's crew so that she could buy the island back and prevent more deaths.
Axis Powers Hetalia: Just about any occupied nation shows signs of this, though they're not necessarily happy about it. But a few really stand out:

Jinto's father in Crest of the Stars was viewed as this after he surrendered to the Abh in exchange for making Jinto a first-generation Abh noble.
Fables has a story involving Icabod Crane and Cinderella, who're both secretly collaborators for the Adversary. Except Cinderella is actually a mole for Bigby Wolf, sent to ferret out Crane's treachery. When caught, Crane tries ineffectively to claim that he was also pretending to collaborate in order to ferret out traitors. It doesn't work.
Trusty John from the same series is another example, although he was forced to do so by his oath to his master, now a vassal for the Adversary. After death he becomes a faithful servant to Flycatcher, however, in contrast to Shere Khan and Bluebeard, who try to sell out Haven to the Adversary.
In Aeon Entelechy Evangelion there are Migou "cultists", sleeper agents who truly believe that Migou are the good guys in the Aeon War (which is true, from a certain point of view).
In Winter War, when Seireitei is surrendered to Aizen's forces and he puts Gin in charge of the city to get rid of him, some of the Gotei 13 and the nobility go along with it. This doesn't include any of the captains or lieutenants, but there are enough shinigami left for Gin to set himself up as "soutaichou".
The Immortal Game: All the pony nobles and soldiers who swear loyalty to Titan, Terra, and Empyrean after they take the throne from Celestia. However, it's worth noting that outside of General Esteem and his inner circle (who sought power), it appears that many only did so out of fear and the belief that the Loyalists had no chance to win.
And then there's the PER (Ponification for Earth's Rebirth), who, while not official collaborators, have forsaken their humanity and will ponify any humans that haven't converted yet. Sometimes by force.
Worldwar: War of Equals: When the governments of the world announce the approach of the Race's Conquest Fleet, many UFO and doomsday cults spring up and attack military facilities in order to pave the way for their "alien masters". They all end up in jail.

Theron, the Ephors and Ephialtes are Greeks who help the Persians in Frank Miller's 300. Ephialtes is the only real life example.
Captain Renault in Casablanca is a rare example of a redeemed Collaborateur. While neutral towards the Nazis, Rick, and the occupation in general, he takes up his forgotten Patriotism and helps Victor Lazlo escape Casablanca and Rick escape arrest, going so far as to throw away a bottle of Vichy water towards the movie's end. As part of the setup near the beginning of the movie, the police shoot a fleeing suspect (with expired ID who just happened to be a Free France supporter) dead beneath a poster bearing the visage of Pétain and the words "Je tiens mes promesses, même celles des autres." ("I keep my promises, even other people's.") Anvilicious? Take That? Yes and yes.
Paul Verhoeven's Zwartboek centres around a woman who is asked by the resistance to sleep with various high-ranking Germans in order to spy on them and plant bugs in their offices. After the war, she is set upon, humiliated and nearly killed by a mob.
In the Blade film series, humans who know about vampires but choose to serve them against their own kind are called "familiars". They are easily identified by their glyph tattoos.
Subverted in Ip Man, where policeman-turned-Japanese interpreter Li Zhao is shown as a sympathetic character just trying to survive and attempts to help the titular character by taking advantage of the Japanese inability to understand Chinese. Ultimately he shoots the Smug Snake Colonel Sato, delivering that character's Karmic Death, but is still subject to the Inferred Holocaust. There's also "Fatty" in the sequel to the British, but it turns out he was a Reverse Mole trying to get information against them.
Mr. Yee in Lust, Caution: He's a high-ranking member of the pro-Japanese puppet government in occupied China.
In Hotel Rwanda one of Paul's hotel employees is a virulent Hutu partisan who tells the militia about the location of the Tutsi refugees.

In They Live!, the wealthy elite of society are secretly cooperating with a race of aliens that are slowly taking over everything, effecting a widening financial gap between the poor and wealthy, and are implied to be terraforming the entire planet to fit their native climate. Among them is a former friend of Nada and Frank from the camp. It's all part of the film's political commentary.
In ''Red Dawn (2012) a couple of out-of-town and would-be members of the Wolverines decide to become North Korean collaborators purely out of spite against the Wolverines because they didn't like the war-experienced Iraqi veteran telling them how to handle a gun. They get killed without a second thought in the Wolverine's first major operation.
In World War Z, many humans snapped from the stress of the Zombie Apocalypse and began to act like zombies. The survivors called them "Quislings" after the head of the Nazi collaborationist government of Norway. It didn't fool the real zombies, however...
The renegades in The War Against the Chtorr, cult followers that worship and help the Chtorran invaders. Their numbers increase as the infestation grows in strength — it's not known whether this is the result of an unknown form of brainwashing or simply a psychological/practical response to the overwhelmingAlien Invasion.
In Fred Saberhagen's Berserker series, being what the omnicidal machines call "goodlife" is universally treated as a capital crime. For good reason.
Lotho Sackville-Baggins. By the time Frodo and company leave the Shire, Lotho's been in Saruman's pocket for years, and when the wizard shows up in the Shire, Lotho jumps at the chance to become his enforcer and figurehead. However, Frodo mourns his Karmic Death and insists the other heroes do the same, since he was still a hobbit.
Gríma Wormtounge also collaborates with Saruman in Rohan.
In the Alternate HistoryWorld War series by Harry Turtledove, the Polish Jews flip-flop between helping the Alien Invaders fight the Nazis and helping the Nazis fight the invaders. In contrast, the aliens try to coerce black American soldiers to fight for them, but most of the soldiers play double-agents.
In Kurt Vonnegut's Mother Night the American protagonist is asked to become a collaborator for the Nazis by an American agent to pass information to America. The book is about what being a collaborator does to his soul (and life), even though he knows he is doing it for a good cause.

In A Man for All Seasons, the Duke of Norfolk swears an oath affirming the Act of Succession, but openly admits that he neither knows nor cares whether anything he swore was true or not; he is merely swearing it to go along with everybody else, and avoid getting into trouble.
In Ken Follett's World War II novel Jackdaws, Nazi officer Dieter Frank's French mistress Stephanie works with him to bring down a French resistance circuit, and is loyal to him since he saved her from a death camp. In the end she gets a bullet in her head from a member of the Resistance.

In Timothy Zahn's Blackcollar, The planetary governments of the defeated Terran Democratic Empire willingly cooperate with their alien occupants, the Ryqril. In fact, they actively celebrate the Victory Day, that is the day the TDE officially surrendered to the Ryqril. Subverted in that all government officials are conditioned to be loyal.
Although some, after being deconditioned, still collaborate with the status quo.
The Reynard Cycle: Mosca is a Southerner who seems to willingly be serving the Calvarian general Drauglir in The Baron of Maleperduys. He's treated fairly well by his boss, even though he still calls him a "southern dog."
A large number of these also turn up when Drauglir offers a hundred thousand gold coins for Reynard's head. One of them is Tybalt.
In Doom, the governments of the world surrender to the aliens and assist them with the conquest of Earth. Fly and Arlene call their commander to report in and the resistance base in Salt Lake City is attacked. They learn the hard way that the US is helping the aliens because most of the enemy forces are human.
Citizens/Adepts Tan and Purple (among others) support the Hectare invasion in Phaze Doubt.
Donovan's mother Eleanor is a collaborator of the foulest variety; a self serving opportunist (who intentionally resembles Nancy Reagan) who has neatly deluded herself that she won't be on the next Visitor menu the moment she exhausts her usefulness. She sells out the Visitors the instant it seems the Resistance is winning. She still wasn't willing to shoot her own son when she caught him during one of his missions, as Donovan himself pointed out ("Even you're not that cold, Mother"). She just fired in the air, and then tore her dress to make it look like she'd fended him off.
Daniel Bernstein, an unpopular teenager who finds power by joining the Visitor youth corps; he becomes a despicable bully, betrays members of the Resistance to the Visitors, and personally kills one of them, an old woman who used to be his neighbor. The Resistance retaliates by framing him for their abduction of a Visitor officer; he's dragged off to become food for the Visitors. Karma's a bitch.
Many of the plots of Star Trek: Deep Space Nine deal with real or perceived collaborators with the Cardassian, and later Dominion occupation, including Kira's mother and (arguably) Odo.
After the Dominion takes control of the Deep Space Nine, Kira remains on the station as the representative of Bajor. At first her intention is to maintain the neutrality of her home planet, but after a while she discovers the tragic irony of her slowly slipping into becoming herself what she always despised - a collaborator.
Although, the Federation isn't occupying Bajor or in any way its enemy — it's only that loyalty to her friends and to what's right sometimes conflict with her loyalty to her people. Some of her fellow Bajorans are just a little quick on the Category Traitor trigger.
Secret Army centers around a Belgian café frequented by German officers, which acts as a front for smuggling allied airmen out of the country - until it is trashed by a mob incensed at their "collaboration".
Secret Army'sfar more well known parody'Allo 'Allo! featured a small Story Arc where General Von Klinkenhoffen decided to give René a "collaboration medal" after he unwittingly helped the General. People started vandalizing his café, his allies, La Résistance threatened to shoot him if he accepted and of course, the Nazis threatened to do the same if he refused. Luckily for René, the General changed his mind about giving him the medal.
In the Doctor Who serial ''The Invasion of Time', Gallifrey is invaded by the Vardans and the Sontarans. There's a slimy Time Lord who co-operates with both invaders and with the Doctor, who is pretending to be a collaborator himself.
A major plot point was this in the third season of the Battlestar Galactica re-imaginging, has a number of humans volunteer as security officers to enforce Cylon rule over the human survivors. Gaius Baltar becomes the Cylons' Quisling, though he literally has a gun to his head.
The Nightwatch serves to inform the Clarke government about potential threats to its rule, at least some of them knowing what they were serving.
Also that political officer lady assigned to Captain Sheridan in one episode. She knew the Clarke administration was evil, but she still served it. She even showed just how much her skewed value system affects her judgment when she clumsily tries to seduce Sheridan ''and is honestly surprised when he's not even remotely interested in a totally naked woman offering herself completely to him.
In the Law & Order episode "Night and Fog," the wife in an elderly Jewish couple apparently kills herself through overdose. Further digging on the husband reveals that he was part of the Nazis' brutal ghetto police unit back in the old country. The dishonor is great enough for him to kill to keep it hidden.
Stargate Atlantis: The Wraith regularly wipe out inhabited worlds to feed on the humans. Nevertheless, they also have a few thousand human followers who worship them and are mostly used for infiltration purposes. They're converted by getting fed on repeatedly only to have their lives restored to them. The experience is so traumatic and addictive that they become mindlessly loyal to their Wraith masters. Every other Pegasus human understandably despises them for their treachery.
Dominion has the Black Acolytes, the Cult that still worships Gabriel and the other angels, apparently having deluded themselves into believing that they'll be spared when the rest of humanity is wiped out.
Terry and the Pirates featured several Chinese who were only too happy to collaborate with the Japanese invaders; most notably Warlord Klang.
On Monday Night Raw, Rob Conway was confusingly referred to as a "French Sympathizer" when he joined La Resistance.
Candice LeRae is Canadian but joined Christina Von Eerie's "Team USA" in Smash against LuFisto's Team Canada because Courtney Rush was in the latter group. However, when Rush did not show up, LeRae wanted out but was not allowed.
Changeling: The Lost features both Loyalists and Privateers. Loyalists are changeling who are still in service to the Gentry, either because they were released from Arcadia with conditions or because they're so bent that they see nothing wrong with working with primordial eldritch entities. The Privateers try to abduct mortals or escaped changelings and sell them to the Gentry for fun and profit.
Mage: The Awakening has the Seers of the Throne, the Ancient Conspiracy that follows the Exarchs, the ascended mages who broke reality in the first place and want to break it more so that magic will be their domain and theirs alone. Some of the Seers view the denial of Supernal magic as a righteous thing, akin to keeping a toddler from playing with C4... but many of them admit they're in it for the benefits that come with being part of an overreaching mystical conspiracy.
Warhammer 40,000: The Tau are pretty much the only faction who'll give the others a chance to work with them under their "Greater Good" policy, which clashes with the Imperium's "The galaxy must be ruled by Mankind" policy. However, there are a few who do join, known as gue'vasa, and are equipped with Tau equipment, and as a result every loyalist human army gets bonuses when fighting them.
Dr. Breen from Half-Life 2 was the first human to attempt to negotiate for peace during the Combine invasion of Earth, also known as The Seven Hour War, and was awarded the title of grand overseer of Earth on behalf of the Combine for his efforts.
The Civil Protection Officers from the same game are humans that have decided to become the Combine's occupational/peace-keeping force in return for more rations and better treatment. The Overwatch and other Combine soldiers are similar; although it's implied that they are given their 'augmentations' unwillingly, and forced/reeducated to fight the Resistance, they are promised sexual simulations in return for success in these endeavours.
Judith Mossman is either a redeemed Collaborateur or a double-agent of La Résistance.
In the Nod campaign of Command & Conquer: Tiberian Sun, GDI soldier Jake McNeil (brother of commander Michael McNeil, the GDI player character) doesn't need much prompting to defect to Nod after his capture; all they had to do was parade a pretty woman in front of him, make a baseless claim that the Brotherhood is only interested in peace, and point out that his older brother has a higher position in the military than him.
Saren from Mass Effect has allied himself with the Reapers, a race of machines who aim to kill all sentient life in the galaxy as he believes that servitude is better than extinction. The game suggests that he was completely Brainwashed, however, and in the final confrontation had been forcibly given implants to quash rebellious thoughts. If you have a high enough persuasion trait, you can convince him to redeem himself by shooting himself in the face.
In Final Fantasy XII Vossler subverts this. He seems to be on the party's side before helping Ghis capture them. It's revealed he is still loyal to Ashe, but believes that the only way to protect Dalmasca is to surrender to Archades.
The Goombas in Super Mario Bros. are former citizens of the Mushroom Kingdom who chose to side with Bowser when he first invaded. There are still good Goombas living in the Mushroom Kingdom, though.
In The Elder Scrolls V: Skyrim, the dragons ruled the world thousands of years ago. Some humans resisted and fought the dragons, while others served the dragons. Some even worshipped the dragons, hence the Dragon Priests.
Izebel in Tears To Tiara 2 is an interesting sympathetic case. She was ordered to become one by her ruler, the man she loves just before he kills himself, in order to shield the realm from the worst excesses of The Empire.
Amanda Connor, the ex-wife of La Résistance leader Sean Napier in Exo Squad, collaborated with the Neosapien propaganda machine, believing that would bring peace between Neosapiens and Terrans. Frankly, she was wrong.
Also the Mayor of Phaeton City, formerly known as Chicago.
The Dai Li in Avatar: The Last Airbender, technically even before they joined Azula and the Fire Nation, since they kept Ba Sing Se's superior military might from being used against the Fire Nation.
In ThunderCats (2011) Thunderian General Grune readily turns his coat at Sorcerous Overlord Mumm-Ra's offer of power, and promise to destroy Thundera, but does so because circumstances denied Grune the resources he needed to orchestrate a miltary coup, and become The Usurper of Thundera himself. Grune becomes The Dragon of Mumm-Ra's forces, and exploits his status as a prodigal treasure hunter to re-enter Thundera with a Trojan Horse full of Mumm-Ra's troops, bolstering The Siege on the city.
Numerous examples during World War II, many of which have since become synonymous with selling out one's country to foreign invaders:
The Wang Jingwei government of 1940-1944. Once, he had been the peoples' favoured candidate to take over as head of the Nationalist Party and take the Presidency. He brought a lot of his popular support with him when he joined the Japanese out of the belief that the Nationalist Party forces would soon be defeated and that his defection could make the transition easier and less bloody. The Nationalists fought on and his defection made the situation worse by its effect on morale and the negative associations with the Nationalists. He ended up presiding over an increasingly powerless and unpopular regime until his death of natural causes in 1944. Though he had good intentions for the most part, all people of Chinese culture Under Heaven know his name as a by-word for treachery.
The Vichy regime in France, who were led by genuine French fascists (and some former communists) but mostly consisted of ordinary folks. Philippe Pétain's name is used as a swear word by some French to this daynote It helps that Pétain sounds a lot like putain, which means "whore" and is a common obscenity in France., and the word "Vichy" likewise represents collaboration throughout the Western world — even on this very wiki. Nevertheless, there's some debate about whether Pétain was a true collaborator; his bargaining position with the occupation troops was after all extremely poor.
Norway's Vidkun Quisling and his party Nasjonal Samling ("National Gathering/Unification") created a collaborator government after Norway was invaded by Nazi Germany. The first Quisling government was, however, dismissed by Reichskommisar Josef Terboven, who felt it would only increase resentment against the occupation (he also thought Quisling was a feckless moron), although Quisling remained as head of the "Kommissarische Staatsräte". Quisling was again allowed to set up his "own" government in 1942, in large part because Hitler (never a great judge of character) believed in him. He was so hated that the staunchly anti-death-penalty country made a special exception just for him. His title, "Minister President" was quickly subverted in Norwegian to something like "Minister Pissatrengt", which translates roughly as "Minister leaking bladder"... His name has become a synonym for collaborationists and traitors.
Even the utterly brutal Reichskommisariat governments on the eastern front had collaborators, many of whom came from nations like Estonia who had been recently conquered by Stalin, or from the persecuted Cossacks, and thought they were fighting for their freedom. As can be seen, in real life, this trope is much less black and white.
A complex example are those local militias who initially support the Germans as liberators from brutal Stalinist oppression, who would arguably be Les Collaborateurs to both sides - to the Soviets for siding with the Germans, and to the Germans for their eventual betrayals after the Germans proved even worse. A good example are the Ukrainian nationalists, who were all over the place (and who wound up committing genocide against the Poles), or the Lithuanian Forest Brothers, who carried on guerilla campaigns against the Soviets, then the Nazis, then both Nazis and Soviets, and then the Soviets again. Until The Sixties.
Perhaps the most visible example of this are the non-German Waffen-SS divisions, who actually comprised about 60% of total SS troops, and originated from a veritable smorgasbord of countries. It is notable that French SS troops were some of the last "German" soldiers fighting in Berlin.
There were several instances of militias in former Soviet territories (Ukraine and the Baltics, for example) who rather enthusiastically began slaughtering Communists and Jews, sometimes even before they had been officially conquered by the Nazis
Soviet General Vlasov, after being captured by Germans, performed a Face-Heel Turn and was eventually given a small army to command. To no surprise, as soon as Soviets captured him, he was...disappeared.
The Netherlands had the highest rate of citizens turning in their Jewish neighbors of any of the countries conquered by the Nazis
Goebbels predicted that American Indians wouldn't be loyal to America. "I understand that Colin Ross, whom you know, is a Nazi and should be treated accordingly." So said Harold Ickes. This started with the assimilationist American Indian Federation and its association with the German-American Bund and Silver Shirts. That the swastika is associated with Shock and Awe in Indian cultures was another reason Goebbels thought Indians would support him. As one final push, Germany declared the Sioux to be Aryan. Ultimately, however, it was Defied by the Indians, most of whom were 100% loyal to the United States — the Sioux Nation declared war on Germany before the US did.
On the other side of the war, we have Thailand, which sided with Imperial Japan. note (Although Thailand mainly sided with Japan as a way to exact territory and concessions in Cambodia from France, and because Phibun wanted to spare the nation the brutality of outright conquest by Japan.) Understandably, relations between Thailand and China and both Koreas are strained to this day. The same goes for Iraq.
The Indian National Army (of the Asian subcontinent, not North America) was the brainchild of Bengal socialist Subhas Chandra Bose), who'd witnessed British leadership ravage Bengal with some of the worst famines in human history. After failing to secure aid from the Soviet Union (soon to be a British ally), he created his independence-minded army with help of Japan, staffed by Indian PO Ws taken by the Imperial Japanese Army. After the war, and Bose's death, the British government of India made a point to Un-Person the campaign out of fear of further rebellions and put officers on trial for treason—the last thing India and Pakistan ever agreed upon was defending the accused.
The Ustae or Ustasha regime in Croatia were probably the most hardline among all the Nazi collaborators. The structure of their organization closely mirrored that of the Nazi party, they sent a substantial number of troops to the Eastern Front, and were the only non-Germans to run an extermination camp. Despite initially having substantial support, their brutal campaigns of genocide against Serbs, Jews and Roma soon alienated most of the population, who ended up joining the Yugoslav partisans under Joseph Tito (if nothing less because they saw him as the lesser evil). Today, the term "ustae" is either used as a derogatory term for Croatian ultranationalism, or as a mocking term against political opponents in Serbia. (i.e., Slobodan Milosevic was referred to as "ustae" by his opposers towards the end of his rule.)
Zigzagged with various Southeast Asian pro-independence leaders who collaborated with the Japanese (at least initially) against their imperial overlords—Aung San and Ba Maw in Burma/Myanmar, Sukarno in Indonesia, and Subhas Chandra Bose in India. All these leaders are at least highly regarded (and in some cases deeply revered) by many in their home countries today because they are seen as La Résistance against The Empire rather than Les Collaborateurs.
Benedict Arnold V, a man whose name is synonymous with betrayal in the United States. In Britain he wasn't too popular either: he left behind another loyalist to be captured, was apparently hard to get along with and died in ostracism (although he's remembered slightly more neutrally in Canada, where many of his descendants settled). His betrayal was motivated by (amongst other things) being constantly passed over for promotions or even demoted for political reasons (even George Washington wrote letters warning against politically motivated appointments, with Arnold in mind) and resentment after suffering a leg injury.
Once the British left New York after the war ended, Washington paid very public visits to several notorious Tories (British loyalists) to demonstrate that they'd been working for him during the occupation. He also issued a note of protection to the family of John Honeyman, another collaberator/spy.
In Iraq, rebelling factions often execute Iraqis working with the US-backed government, accusing them of collaboration.
Hamas in Palestine accuses Fatah and especially President Mahmoud Abbas of collaboration with the Israeli occupation. This isn't technically wrong—the Palestinian security forces under Abbas' control do cooperate extensively with the IDF and the Israel Police—but what makes the accusation disingenuous is that this is what the Palestinian Authority is supposed to be doing. You see, the Oslo Accords call for the Palestinians to provide security guarantees to Israel as a trust-building measure; with less violence, Israel is supposed to be more willing to end the occupation and give Palestine its independence.note Unfortunately, with the highly-suspicious and rather stick-in-the-mud Benjamin Netanyahu at the helm, the bar for "security" has been set almost impossibly high. The problem is that Hamas has thus far refused to renounce violence, meaning that the PA and Israel keep arresting Hamas fighters.
The Taliban have executed their own people on accusations of spying, including a a seven-year old boy and a 70-year old woman.
During American slavery there would be black slaves, or even free blacks (some of whom were even preachers) who would rat out other slaves attempting to escape.
Not to mention the very few free blacks who ended up owning slaves themselves.
The Indian wars often had this. The Pawnee aligned with the United States, but over time, people like Red Cloud and Spotted Tail also fell under United States influence.
French couturier Coco Chanel was accused of this when she had an affair with a Nazi spy. But then the British and the Americans acquitted her because of her wide influence.
