->''"Five years ago, I lost thirty thousand men in the blink of an eye...and the world just ''fuckin''' watched. Tomorrow, there will be no shortage of volunteers, no shortage of patriots. I know you understand."''
-->-- [[spoiler:General Shepard]] of ''ModernWarfare 2''

Sometimes directly pointed out by a war veteran or someone with a lot of experience in life, this trope is about some society growing complacent with peace and reluctant to think anything bad can happen. Little do they know that TheEmpire over there is gearing up for the war that will slaughter thousands, if not millions, of civilians. Sometimes done {{anvilicious}}ly, sometimes it's just part of the plot. Don't be surprised if the society heavily frowns upon violence, even in self-defense.

The WideEyedIdealist trope applied to entire ''civilizations''. Expect the heroes to try to stop the evil plan, either by alerting the populace or by fighting behind the scenes. If they fail, expect their country to be a SoiledCityOnAHill or an EasilyConqueredWorld. If there is an epilogue, expect AndManGrewProud.

This is also frequently a motivation of villains who want to keep their people "strong" and "pure" - they are often TheSocialDarwinist.

Avoiding this is one of the main points of JapaneseSpirit.

[[folder: Anime and Manga]]
* In ''Manga/AttackOnTitan'', most of humanity got comfortable after a hundred years of peace and were completely unprepared for the first titan attack. Eren even chewed out Hannes and the Garrison troops for drinking on duty since they thought titans wouldn't be able to breach the wall. Afterwards, the Garrison was somewhat more capable at dealing with titans. The only group that didn't slack off during this period was the Survey Corps and that made them the most experienced and prepared to deal with titans.
* ''Manga/{{Bleach}}'': In the Thousand Year Blood War arc, the ancient war between [[{{Psychopomp}} Shinigami]] and [[ArcherArchetype Quincies]] flares up again. It's revealed that [[AloofAlly Uryuu Ishida's]] arrival in Soul Society two years previously had made [[MadScientist Mayuri]] realise a future Quincy assault would occur - and succeed - but [[BadassGrandpa Yamamoto]] dismissed his [[CassandraTruth warning]] as paranoia, so did nothing to prepare for it. When [[TheEmperor Yhwach]] and Yamamoto confront each other, Yhwach reinforces Mayuri's accusation, observing that the Shinigami's genocide of the Quincies two centuries previously created peace for the first time - and as a result, they became complacent and soft, making it easy for the Quincies to commit a retaliatory genocide before the Shinigami could muster any kind of meaningful defence. As a result of the Shinigami oversight, the only Shinigami within the Gotei 13 who has any meaningful knowledge of Quincies is Mayuri.

[[folder:Comic Books]]
* ''{{Dreamkeepers}}'' has it so that using your powers is grounds for exile. This is due to in part of the [[EldritchAbomination Nightmares]], the reason for their powers in the first place, hiding for a long time and having double agents in the government.
* One of Creator/AlanMoore's "Future Shocks" for ''ComicBook/TwoThousandAD'' is about a legion of soldiers sent into space by their home planet's emperor after all their enemies there have been defeated. Their mission is to travel through space in a straight line and destroy everything in their path until they reach the end of the universe. After over a billion years, the soldiers find a planet up ahead that once had the reputation of a great empire but has since become "soft and flabby." They decide to lay waste to it and later discover that it was their own home world, because the universe is curved and circular.
* In one ''{{Asterix}}'' album, Julius Caesar scolds his senators:
--> Caesar: "Look at yourselves! You have become decadent! All you think about nowadays is eating and sleeping!"
--> Senator (waking up): [[IResembleThatRemark "What? It's lunchtime already?"]]
* The backstory to the ''ComicBook/SilverSurfer'' involves this trope: his home planet Zenn-la used to have a space programme, but the people dismantled it and went home to go CrystalSpiresAndTogas, meaning all of them would have been wiped out by Galactus if Norrin Radd hadn't saved them by sacrificing himself to become the Surfer.
* In many modern incarnations of Superman, this is shown to be General Zod's major complaint before Krypton's destruction. Notably, he's usually shown to be right: either their lack of military bites them in the tail when Brainiac comes, or their lack of a space program bites them when the planet explodes, [[BreadEggsBreadedEggs or both in succession]].

[[folder:Film]]
* Pretty much the point of Richard Harris' final speech in ''[[http://www.youtube.com/watch?v=a9DHOnUngxQ Cromwell]]''.
* ''TwilightOfTheCockroaches''. A society of cockroaches, flourishing under the passive acceptance of a depressed bachelor, is completely unprepared when he begins dating a neat freak...
* A big theme in ''Film/TheDarkKnightRises'' is how decadent and complacent Gotham City has become in the eight years of peace that resulted from the Dent Act. The police are unprepared when a new supervillain emerges, and the social shift brought about by this complacency makes the people of Gotham easy pickings for Bane's manipulations.
** Bane even sums it up to Batman in their first fight:
--> '''Bane''': Peace has cost you your strength. Victory has defeated you.
* In ''Film/{{Skyfall}}'', when asked by a government committee if MI6 is relevant to the modern world, M responds that there should be an even greater focus on espionage to battle increasingly decentralized modern threats.
* In ''Film/StarTrekIntoDarkness'', Harrison claims the Federation has become an easy target, despite the peace and safety they pretend to have.
-->'''Harrison:''' You think your world is safe? It is an illusion. A comforting lie told to protect you.
** This is the motivation of Section 31, as well.
* By the year 2020, the Jaegers in ''Film/PacificRim'' have racked up such impressive record of killing {{Kaiju}} that most pilots treated it as simply another chance to increase their kill score. The public saw the Kaiju as means to entertainment, such as making toy lines and television gags. Cue the MassOhCrap when people begun to realize that the Kaiju are adapting to fighting Jaegers by targeting the pilots and its power sources. A mere five years later, the Jaeger program is on the verge of a shutdown because Jaegers are being destroyed faster than they could be built.
* Done subtly with the Las Vegas attack scene from ''Film/{{Godzilla 2014}}''. The female M.U.T.O. has escaped from Yucca Mountain and is rampaging through the Entertainment Capital of the World on its way to meet its mate on the West Coast. We get a shot of the inside of a busy and dangerously unaware casino where the people are so preoccupied with the slot machines that they all ignore the news report on the interspersed televisions warning about the monster. When the M.U.T.O.'s {{EMP}} suddenly knocks out the power in the building, everyone's reaction is a mass groan of annoyance, then an abrupt switch to screaming panic when the M.U.T.O. crashes through the roof.

[[folder:Literature]]
* The UrExample is from Herodotus's ''Literature/{{Histories}}'', [[OlderThanFeudalism written in the fifth century BCE]]. King Croesus [[note]]Ever hear the phrase "rich as Croesus"? Yep, that's him.[[/note]] asked Solon whether he was not the happiest man on Earth. Solon answered "Count no man happy until he is dead", and cautioned that fate could change for him. He pooh-poohed this idea... until after he had his empire utterly destroyed by Cyrus the Great.
** [[UnbuiltTrope Of course, there are a few differences between this and the modern trope]]: He was the one who went to war, after asking the Oracle of Delphi for the result of this, and being told that it would result in the fall of a great empire if he did. [[ProphecyTwist The great empire that fell? His own.]]
* This is part of the premise of [[Literature/KnownSpace the Man/Kzin]] Wars. Humans have used a combination of social programming and chemical cocktails to remove humanity's collective balls. [[SuperweaponSurprise We get them back, though]].
* Saki's "When William Came".
* Mentioned several times about the United States and Britain in ''Literature/TheWindsOfWarAndWarAndRemembrance''.
* A theme in ''Literature/CurseOfTheWolfgirl'' is that the leaders of the werewolf clans have become complacent about the idea of Scotland being a fortress against [[BigBad werewolf hunters]]. Naturally the big set-piece battle of the book is in Edinburgh.
* In ''Spirit Fox'' by Mickey Zucker Reichert and Jennifer Wingert, the nations of a continent make peace after a war, going so far as disbanding their armies and having the priests announce that their respective gods have combined into a new pantheon and declared a new era of peace and prosperity, and that henceforth military preparations are unnecessary and an evil in the sight of the gods. Twenty years later, when nearly everybody's become comfortable, an invasion force shows up from the next continent over. After that, things happen just as the trope description says.
* Society in ''Literature/CodexAlera'' had become complacent due to dependence on furycrafting. The power a person possessed determined their place in that society, with the most powerful becoming the High Lords while the least powerful had no place in the citizenry. Naturally the people without strong furycraft would develop strong minds that ''could'' enhance society, but because they didn't have strong furycraft they were always ignored. The people with strong furycraft were content with where society was and had no drive to enhance it, which promoted stagnation. Tavi recognized this problem [[spoiler: and convinced Alera to reassign furycrafting to anyone based on merit, giving strong furycrafting to those with strong minds to use it productively.]]
** It also applied to the army. The Legions had fought and destroyed a number of hostile races over the centuries, but because of all those victories, it was entirely possible that you could go through a tour of duty in the Legions without fighting a single major engagement if you weren't serving on the Shieldwall, because the other regions no longer bordered any enemies. This costs them dearly in the initial battles against the Vord.
* In the Literature/HonorHarrington series this is the job of the Solarian League. Over 80% of human space is dominated by the League, with slow outward growth giving new systems entry via the Office of Frontier Security. No fleet battles fought for 300 years, with no real wars fought since the League was founded. They boast ten thousand superdreadnaughts. The Solarian League is the Biggest, Most Powerful Star Nation Man ever saw. But the political mechanisms running the league are ineffective. The politicians have no real power because the founders didn't want a real central government (think something like the US under the Articles of Confederation mixed with the EU and older Polish laws). The Bureaucracy has the real power, but even that is still pretty limited. The power is conserved mainly within families, subverting the democracy and merit requirements for politics. Any member system can veto actions of the elected government, so the Bureaucracy endeavors to make nothing real come up for votes. Because they are big and impossible no one minds this, despite this meaning their Navy is split in two, with the light elements mostly part of Frontier Fleet whose job is to suppress pirates and those who'd rather not join the Solarian League, and the rest in the corrupt Battle Fleet whose positions are on patronage. So bad is it, that sending out ''any'' report challenging any assumption the fleet runs on is career death. Of those 10,000 [=SDs=], only 2,000 are in service, 8,000 are mothballed (and some sold off piece by piece) and nearly all are several hundred years old and only periodically updated. A few are made each year mostly as politics and keeping the skills around. In their first real fight they lose dozens of [=SDs=] to light fleet elements due to incompetent commanders and their intended victims having been continuously upgrading their hardware for over twenty years. OhCrap.
** Baron High Ridge and Edward Janacek started pushing the Manticoran Navy down this path between Oscar Saint-Just's death and the restarting of the Manticore-Haven War, despite Honor and Earl White Haven's best efforts to the contrary.
* [[Creator/AndreNorton "So be it--" That was Lugard once more, but he sounded very tired.]] "'And when Yamar lifted up his voice, they did not listen. And when he cried aloud, they put their hands to their ears, laughing. And when he showed them the cloud upon the mountains, they said it was afar and would come not nigh. And when a sword glinted in the hills and he pointed to it, they said it was but the dancing of a brook in the sun.'"\\
The Cry of Yamar! How long had it been since anyone had quoted that in my hearing? Why should anyone on Beltane? Yamar was a prophet of soldiers; his saga was one learned by recruits to point the difference between civilian and fighting man.
* Humans on Earth in Creator/DanSimmons's ''Literature/{{Illium}}''. It's taken to the extreme by the fact that they're not even in charge, but rather being baby-sat by a bunch of robots, so that they don't have to know how to do ''anything''. By the end, they're having to learn how to fight again.
* According to the ''Muqaddimah'', a 14th-century Arabic text by historian Ibn Khaldun, this is an important factor in civilizations' decline. The theory is something like this: Early generations of a city have a strong sense of community and an ability to defend themselves, because they're not far removed from dwelling outside a city. The later generations become complacent, relying on the city instead of each other, and either don't see a threat coming or can't deal with it. Changes in the rulership of Islamic Spain, in which a decadent dynasty of Umayyads was replaced by a group of religiously zealous desert dwellers from North Africa, were almost certainly an influence on Ibn Khaldun's theory.
* In ''Literature/HarryPotter'', Harry has trouble convincing the Wizarding World that Voldemort has returned because the Wizarding World really doesn't want to believe it. They spend a great deal of time and effort smearing Harry and Dumbledore, time and effort they could have spent preparing for the Death Eaters. By the time the Ministry finally can't deny the reality of Voldemort's return any longer, it's far too late.
* In Creator/VladimirVasilyev's ''Literature/WolfishNature'' duology, the AlternateHistory dog-humans are masters of genetic engineering. In distant past, they have managed to breed out the so-called "wolf gene", which allowed one to kill without remorse. Now, killings are so rare that cops aren't prepared to deal with murderers (who are deranged psychopaths). Anyone who kills is likely to go insane, and nations, no longer able to wage wars, have taken the spy game UpToEleven. Special agents are the only ones trained to kill, and even then extensive psychological therapy is necessary after the fact. Then the world finds out about an isolated enclave of unmodified "wolves". The wolves reveal that they were abducted by an alien empire prior to the Bio-Correction (the removal of the wolf gene) to be used as mercenaries in interstellar wars and have returned after the end of their tour of duty to find a world of pussies, totally unprepared if Earth happens to become the target of an alien race. The ending reveals that [[spoiler:the Bio-Correction was the cover story for a massive PR campaign to convince people they're incapable of killing, making it a case of ClapYourHandsIfYouBelieve]].

[[folder:Live-Action TV]]
* ''Series/StarTrekTheNextGeneration'' was a good example of this. In the words of [[http://www.youtube.com/sfdebris sfdebris]], the Federation had grown arrogant in its beliefs; exploration was their main goal and they believed that they were prepared for anything. Then Q appeared and put them in their place, introducing them to [[YouWillBeAssimilated the Borg]], forcing Picard to acknowledge that they're not ready for ''everything'' that's out there. Picard even tells Guinan at the end of the episode that the Federation may have needed "a kick in our complacency".
** And then a little over a year later the Borg proceeded [[CurbStompBattle to wipe out a 40-ship fleet with a single vessel]].
* In the original series ''Series/DoctorWho'' episode "[[Recap/DoctorWhoS15E6TheInvasionOfTime The Invasion Of Time,]]'' the Time Lords take their indestructible force field so much for granted that they really have no other defenses (or at least none that are up to fighting [[spoiler: Sontarans.]]) Naturally, the force field gets breached.
* ''Series/BattlestarGalacticaReimagined'': Commander Adama believed this of the Colonials, forty years after the Cylon War. And he didn't just mean in terms of military strenth and readiness to fight: he meant ''morally'', as the Colonies had forgotten the reasons behind the war and their responsibilities to the Cylons. You know how this ends.
* ''Series/{{Andromeda}}'' starts with a Nietzschean rebellion with a fleet of 10,000 warships attacking the [[TheFederation Commonwealth]]. While the [[SpaceNavy High Guard]] fleet numbers ten times that much, those ships are spread out all over the three galaxies that are part of the Commonwealth. Additionally, the Commonwealth hasn't had a real war in over a millennium. In fact, Hunt ''not'' using Nova Bombs to obliterate the entire Nietzschean fleet is seen as further proof that the Commonwealth softens people. By the time the final big battle of the rebellion takes place, the Commonwealth is down to about 100 warships.
* ''Series/{{Dominion}}'': [[CorruptPolitician David Whele]] feels this way about Vega, saying that the city is so well defended that its people have become soft and begun to forget what a threat the angels pose to their existence. To the point that he has a captured angel brought into the [[BreadAndCircuses Jubilee]] to be slaughtered, just to remind people of the danger... and when this results in a rampage and angelic attack on the city, he still sees things as a win, since people now remember the true nature of the situation they're in.

[[folder:Video Games]]
* The ''StarWarsTheOldRepublic'' has this pointed out at least three times in ''KnightsOfTheOldRepublic'' 1 & 2.
** This is also what Darth Malgus tells the viewer as he narrates the ''Deceived'' trailer for TheOldRepublic. Given how absolutely unprepared the Republic and Jedi were for the Sith Empire's reemergence and assault on Coruscant, he seems to have a decent point.
** And yet, despite everything that happened to them, the Jedi and Republic get themselves back in shape within a generation, kick Sith ass all over the Galaxy, and reclaim a lot of their lost glory. It gets to the point where the Sith, suffering from inherent problems in their own society, are barely hanging on to power by the time ''Rise of the Hutt Cartel'' starts.
* This is a major element of the ''Franchise/MassEffect'' saga. The Citadel races desperately want to believe everything's still going fine - the [[BugWar Rachni]] are a memory, the [[ProudWarriorRaceGuy Krogan]] are irrelevant, the [[RobotWar Geth]] have been defeated... and they refuse point-blank to acknowledge the return of the [[EldritchAbomination Reapers]]. Only the humans, energetic newcomers to the galactic scene, are prepared to acknowledge the existence and terrible threat of the Reapers... And that only lasts until the sequel, when humanity's increased influence on galactic affairs has led to them becoming just as complacent as the others.
* Following the centuries that have passed between the Fourth Blight and the Fifth in ''VideoGame/DragonAgeOrigins'', most people of Thedas have forgotten the dangers posed by the Darkspawn. As a result, the public support of the Grey Wardens has deteriorated and the new Blight catches almost everyone with their pants down. [[spoiler:In a subversion, however, the Fifth Blight is ended by the PlayerCharacter's efforts within a year after it began, before it even has a chance to affect more than one nation, going down as the shortest one on record. Whether this will lead to even more complacency regarding Darkspawn remains to be seen.]]

* Alpha in ''[[TheCyantianChronicles Akaelae]]'' comments that due to the council whittling away the space navy, he can't do anything to help Celina escape. [[spoiler:Not that it stops Celina returning on her own. Expect there to be further repercussions in the future as well.]]
* The First Dalek Empire has a ''serious'' issue with this (increased dependency on computers and genetic engineering to make the race more subservient to the will of the Golden Emperor), to the degree their top MilitaryMaverick is willing ''and'' able to defect and ultimately steal away two complete armies by sheer force of charisma and brute intellect to create his own Empire to challenge the stagnation of the First - the Webcomic/SecondEmpire of the Daleks...

* In ''WebVideo/CounterMonkey'', Spoony uses this to his advantage during a ''TabletopGame/VampireTheRequiem'' LARP. He made a [[FriendlyNeighborhoodVampire Carthian]] vampire, but since the LARP was built around a BalanceOfPower between [[DeadlyDecadentCourt The Invictus]] and the [[CorruptChurch Lancea Sanctum]], he was forcefully railroaded into joining the Lancea Sanctum. However, because of said balance of power, they felt so confident in their security that they didn't do weapon checks anymore, allowing the [[ScienceHero scientifically minded]] and [[BewareTheNiceOnes very disgruntled Carthian]] to craft and sneak in enough homemade [[StuffBlowingUp Semtex]] to obliterate the entire Elysium (effectively doing a player-based RockFallsEveryoneDies on the [[KillEmAll entire LARP group]]). [[SoreLoser The DM wouldn't permit it, despite it being within the rules]], but managing to pull off that stunt was revenge enough.

[[folder:Real Life]]
* Often mentioned, especially during the 1960s and later, how the United States has become weak and decadent thanks to the "[[AcceptableLifestyleTargets dirty hippies]]", so now we are in danger from the DirtyCommies.
** This argument is coming into sharp focus once again due to America's repeated humiliations on the world stage ([[RuleOfCautiousEditingJudgment real or imagined]]). It was also part of the reason that ''[[EducationMama Battle Hymn of the Tiger Mother]]'' caused such a stir in the US of A, with reports of declining education standards ''vis-a-vis'' the Far East.
* In fact, this concept is ingrained in the Chinese's view of their own history. At the beginning, a particularly talented warlord carves out a petty fief and, after much hardship, unites all of China under the banner of his dynasty. The first few emperors remember the hardships of the warring era and the fate of the tyrant of the previous dynasty, and so apply themselves to governing wisely. From this, the dynasty develops and reaches its zenith. But slowly, the following emperors let the power get to their heads and become soft or tyrannical, corruption and rebellion sets in until the dynasty falls apart. And in the ensuing chaos, some other talented warlord can rise, starting the cycle all over again.
* This was pretty much a hallmark of the history of Central Asia, where a virile dynasty of steppe warriors would take over a corrupt or effete civilization only to become decadent themselves and be kicked out later by a fresh batch of nomads.
* This trope is actually a rather accurate representation of typical human behaviour during eras of economic bubbles. For a simplified example, in Ireland[[note]]a country that had pretty much always struggled with poverty (even after the British Empire relinquished all but 6 counties from their rule)[[/note]], the 'Celtic Tiger' boomed from the mid-1990s to the late 2000s on the back of a quickly-expanding property market and the increase of professional workers spawned by the growing 'knowledge economy'. For the first time, Ireland was no longer considered a Third World country, and, in fact, had skyrocketed to becoming one of the world's wealthiest countries. However, in spite of the warnings of economists across the country, the bubble burst '''hard''' as it emerged that corruption was rife through both the banking institutions and property developers in the duraion of the boom, causing Ireland to fall billions of Euro in its national debt (which, although coinciding with the then-emerging global economic crisis, was nonetheless a separate issue entirely). Lower-level workers in both the private and public sectors, having grown accustomed to their new, more affluent lifestyles[[note]]many of which being also in possession of property outside their own homes, on the advice of the government that they would sell well later, only to be left with near-worthless land now[[/note]], were now facing mass pay cuts across the boards, while the toxic banks were being bailed out with money that would never be seen again (and, judging by the reluctance of the higher-ups to change their ways, to little effect). In short, the people (and, to a more worrying extent, the government) had grown reckless and careless with money, over-relying on credit for payments and making foolish purchases, only for it all to bite them later in the face of the current recession[=/=]depression.
* Anti-racism advocates often argue that focusing on past advancements in race relations (i.e. the statement, "Martin Luther King fixed racism, we don't have to worry about it anymore.") can blind people to ongoing and persistent obstacles to racial equality.
** Sometimes the attempt to avoid complacency sort of creates complacency. Cry wolf (put out accusations of racism at the drop of a hat all the time) too many times and people are less likely to listen to you when you actually have a legitimate point to make.
