-->-- '''Manga/BlackLagoon'''

The USA is capable not only of exterminating with its long-range nuclear arsenal, but also using ground forces to successfully invade and occupy any country on Earth including China and India. Given that the USA chews through about half the entire world's military spending ''on its own'', it might still have this kind of power in forty years or so.

Thus, a common conceit of sci-fi and some {{satire}} is for The USA to take over the world. Jokes about entire countries becoming the n+50th state are common. The recent economic shift in the new millenium will put this theory to the test.

!!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* In ''Anime/BubblegumCrisis'' almost everybody has at least half-Western name, and there's a black chief of police, among other decidedly un-Japanese details in this futuristic city of Megatokyo. It's probably a direct ShoutOut to ''Film/BladeRunner'', which featured a huge Japanese population in America.
* The second season of ''Anime/DarkerThanBlack'' reveals the motive of the U.S. involvement in the GambitPileup being that America wants to be a superpower again. The ending has [[spoiler:American forces invading Japan, and it's implied that they succeed to some degree.]] Of course, this is one of the ''less bizarre'' events that happens in [[GainaxEnding that ending]].
* In {{Gundam 00}} America clearly dominates the Union powerbloc that includes the entire western hemisphere, plus Japan.
* In ''Anime/CodeGeass'' most of the world is dominated by the Holy Brittainian Empire, but Britain itself has been lost. However, the American Revolution was crushed and thus the colonies became the new base of the empire, which proceeded to take over the entirety of both American continents.
[[/folder]]

[[folder:Literature]]
* In ''JenniferGovernment'', the USA has absorbed all of North and South America (except Cuba), the British Islands, India, most of South East Asia, and most recently Australia into a single market. Russia is in the process of being assimilated.
* Mention is made of a very militarized American Empire in ''{{Mortal Engines}}'', though the story takes place {{After the End}} and it had already fallen.
** It's more America Destroys The World. It's mentioned by a character that "the old American Empire was quite insane at the end."
** Both of the series' [[WaveMotionGun important]] [[KillSat superweapons]] are explicitly stated to be American, as well.
* A very popular trope in modern Russian sci-fi. The cliche goes something like this: The U.S. either create some sort of world government or otherwise subjugate most of the world and then invade Russia, the last country keeping them from complete world domination. They either get the shaft during the invasion or succeed in conquering Russia, only to be toppled several years later by a highly {{badass}} Russian LaResistance.
* The ''Clone Republic'' series by Steven L. Kent is set in 2508, after the United States took over the world and then became a sort of Constitutional Oligarchy called the Unified Authority.
* The titular ''CoDominium'' is [[WeCanRuleTogether an alliance of the United States and the Soviet Union working together to dominate Earth]].
** Something similar is suggested in side material to Franchise/{{Dune}}.
* In ''Literature/LastAndFirstMen'' by Olaf Stapledon, the First Men (that is, us) end up being split between US and Chinese spheres of influence. The US eventually tips it, and remains dominant until the entire society collapses due to an energy crisis.
* The ''Lionboy'' book trilogy by Zizou Corder includes several off-hand references to 'the Empire'. It takes a bit of reading between the lines for a while to realise that this means America.
* In America's Galactic Foreign Legion, "the old United States decided to stoop pussyfooting around and opened a can of whupass on Islamic fascist terrorists, communists, greeners OPEC, China and Democrats. The United States conquered the world, creating a new world order, stable food and energy prices and eliminating the threat of weapons of mass destruction ever being used between nation states." America takes over more than just the world.
* Indirectly in the {{Lensman}} series; the Galactic Patrol have their headquarters in New York City due to its role as the leading financial and political powerhouse of Earth and therefore the Solar System. It has rivals in London, Chicago and [[TheGreatPoliticsMessup Stalingrad]], but is way ahead of them.

[[folder:Live-Action TV]]
* Background material for the ''Series/{{Firefly}}'' 'verse establishes that [[AmericaTakesOverTheWorld America]] and [[ChinaTakesOverTheWorld China]] [[WeCanRuleTogether took over Earth That Was together]].
* The seal for the President of Earth on ''Babylon5'' is clearly derived from the Seal of the President of the United States.
* The symbol for Earth Starfleet on ''Series/StarTrekEnterprise'' suggests that it evolved from NASA. Or perhaps not; there are other space agencies with symbols just as similar (though this might be partly a result of influence from previous Star Trek shows).
[[/folder]]

[[folder:Music]]
* The album ''The Uprising'' by {{Muse}} takes place in a world where a coalition government rules all of the Norther Hemisphere, the United States of Eurasia
[[/folder]]

[[folder:Video Games]]
* ''VideoGame/FrontMission'' depicts both North and South America merged into one nation called the USN.
* ''{{Section 8}}'' had the United States become a repressive interstellar empire, somehow forgetting the ideals it was founded on along the way.
* ''VideoGame/{{Fallout}}'''s [[JustBeforeTheEnd pre-War]] backstory has the US annexing Canada and successfully invading mainland China in retribution for their invasion of Alaska. Not a full example, for [[TheEndOfTheWorldAsWeKnowIt obvious reasons.]]
* This is the highest objective that can be accomplished by the Americans in ''VideoGame/RiseOfNations: Thrones and Patriots'' in three different campaign modes. Lesser victories such as simply becoming the dominant power on the planet are also possible.
** World mode is an anachronistic free-for-all between almost all historic great powers, set from the beginning of history up to the future - you can also play as the Americans.
** America takes a bigger role in New World mode, your goal being to break free from British rule, conquer all of North America at least, drive out every last European power from both American continents, and attain a specific amount of tribute.
** In Cold War mode the Americans are one of two playable factions, the other being the Soviets. As the Americans you ultimately need to conquer the Warsaw Pact and the Soviet Union and subjugate the rest of the world as your client states (the latter is implied by the former). You can do this by money (one victory condition is having an industrial output lead over the other bloc by more than 50 - this can be done either by building up the US and its allies or initiating "police actions" on nonaligned countries), conventional force (ground invasion of the Soviets or its allies), or [[NukeEm nuclear exchange]] (only possible if you have enough nukes to irridate all Soviet territoies but the reverse is not true).
* In the ''Franchise/MetalGear'' series it is established that there was an international conspiracy during the time of the First World War where America, China, and Russia made a secret pact where all 3 of them would work together to make a better world. After World War II the Cold War splintered the group, but eventually the American faction took over all of the group's power and renamed themselves the Patriots. The Patriots as we see them by the time of Metal Gear Solid 2 and 4 have consolidated economic, cultural, and technological dominance over most of the world and are taking the final step in world domination by creating a computer system that will monitor every single citizen on Earth that has nano-machines in their bodies and can control all information that flows through the Internet. Fortunately this conspiracy is finally put to an end by the end of the series.
* In the ''VideoGame/{{Civilization}}'' series, it is possible for the United States to conquer the world. ''Civilization V'' promotes this by making the American special ability (ManifestDestiny) having tiles cost 50% less, effectively letting it swallow up twice as much territories as other empires. The ''other'' American civilization, the [[UsefulNotes/NativeAmericans Shoshone]], get a similar play on expansion - their cities are created with twice as much territory as any other civilization.
* In ''VideoGame/CommandAndConquerRedAlert3'', this is [[ImpliedTrope implied]] by the U.S. Vice President in the Allied ending.
[[/folder]]

[[folder:Web Comics]]
* It's not stated how many other countries they might have taken over, but America apparently annexed Canada at some point in the past of ''Webcomic/AMiracleOfScience''.
* One of the villains from ''Webcomic/PrincessPi'', an American dictator named, "Princess Ip", works to make this a reality.
[[/folder]]

[[folder:Web Original]]
* The premise of the SurvivalOfTheFittest alternate setting ''The Program''.
[[/folder]]

[[folder:Western Animation]]
* ''WesternAnimation/{{Futurama}}'' varies between the presence and absence of this trope depending on the [[RuleOfFunny needs of the joke]], but it most commonly presents Earth as a single political entity, ruled from Washington according to the American political model. Earth's flag is just the modern American flag with the stars replaced by a globe [[HemisphereBias centred on America]]. Also, in one episode, Richard Nixon was initially unable to run for president of Earth due to already serving two terms, indicating continuity between the modern US government of the 1970s and the Earth government of 3000.
* In an episode of ''WesternAnimation/TheSimpsons'', while at a beach in Rio, the lifeguard was able to tell that Homer was an American because he wore [[http://afeatheradrift.files.wordpress.com/2009/04/try_and_stop_us.jpg a shirt]] where UncleSam was consuming the world with the lines "try and stop us" on it.
** In one of those "future" episodes, there'll be a 51th state named "Saudita Israeli".
* In the future of ''Disney/MeetTheRobinsons'' Canada is referred to briefly as North Montana.

[[folder:Real Life]]
* Perhaps the most dramatic time the USA explicitly took possession of land besides the contiguous United States by force was in the Spanish American War, and seized territory generally either given back to its occupants or agreements were signed to do so--however some territories, such as UsefulNotes/{{Guam}}, remained in US possession. During that and later conflicts, the USA's preferred method was to make economic partners of defeated nations and leave a few military bases behind, but restore political and military independence. However, in the Pacific, the USA seized the Kingdom of Hawaii by force, dismantling the Hawaiian monarchy in the process. It also took American Samoa following a conflict with the islands' previous imperial overlord, Germany--this involved partitioning American Samoa from the rest of UsefulNotes/{{Samoa}}.
* During the run-up to UsefulNotes/TheAmericanCivilWar, both sides were looking to expand their territory, since each new state boosted the faction's power in Congress. For the North, this meant grabbing as much of British North America (now UsefulNotes/{{Canada}}) as possible, with the most widespread call being for the complete annexation of [[TheOtherRainforest the Oregon Country]] up to the border with (then-Russian) UsefulNotes/{{Alaska}}; the slogan was "Fifty-Four Forty or Fight!", referring to the 5440′ North line of latitude where the Oregon Country ended. From there, it was hoped, the North-West Territory and Rupert's Land, now cut off from the Pacific, would also become American. (Ultimately, the US only got the areas south of the 49th parallel minus Vancouver Island; the rest became the province of British Columbia.) Even a few years after the Civil War, the US' purchase of Alaska was at least partly motivated by the dream of adding the vast expanse of western Canada to the Union by establishing a US outpost on that country's western frontier.\\
\\
Meanwhile, Southern politicians and businessmen felt that, since slavery was explicitly prohibited north of 3630' North, it was implicitly allowed anywhere south of that line. As such, many efforts were launched to annex or conquer UsefulNotes/{{Cuba}}, UsefulNotes/{{Mexico}}, and other nations in Central America and the Caribbean. The UsefulNotes/MexicanAmericanWar was fought for this purpose, President UsefulNotes/JamesKPolk authorized spending up to $100 million to buy Cuba in 1848, Confederate President Jefferson Davis spoke of "new acquisitions to be made south of the Rio Grande", and Confederate Naval officers were dispatched as far as the Amazon delta in UsefulNotes/{{Brazil}} to survey the area, supposedly to map shipping routes but also taking notes on local militias and separatist movements.
* Cuba, The People's Democratic Republic Of Korea, and other similarly colourful regimes have publicly and repeatedly referred to the OAS, NATO and the USA's major Non-NATO allies (e.g. Japan, Australia) as "the whores of America" and call them the USA's version of TheEmpire.
* The internet. Around 90% of all porn sites launched in the United States. A country in which it is possible by law to ban the release of pornography. This of course gives people the idea that most internet users are from the United States, which in turn leads people to believe that their culture will be destroyed by it and that everyone in the world will adhere to the cultural values and norms of the USA.
