Through President of the United States, Invasion and Canada

Trump first stated his desire to annex Greenland during his first presidency; he has pursued a campaign to acquire Greenland during his second presidency. He has also suggested annexation or taking control of Canada, Mexico, the Panama Canal, the Gaza Strip, and Cuba. After proposing an invasion of Venezuela, Trump's second administration removed President Nicolás Maduro as part of Operation Absolute Resolve and stated the U.S. would "run" Venezuela; the Venezuelan government, led by acting president Delcy Rodríguez, remains in place but is far more amicable to American interests than it was under Maduro. Amid the 2026 Iran war, Trump lauded about invading and seizing control of both the Strait of Hormuz and Kharg Island from Iran.

Trump's determination to treat the Western Hemisphere as a U.S. sphere of influence has been characterized as a revival of the Monroe Doctrine in what has become known as the Donroe Doctrine. On his orders, U.S. federal agencies adopted new names for shared international waters, renaming the Gulf of Mexico as "Gulf of America" in 2025 and Lake Ontario as "Lake America" in 2026. Deputy Chief of Staff Stephen Miller and Secretary of State Marco Rubio defended the second Trump administration's foreign policy as a matter of operating as a superpower nation and for national security purposes. Numerous politicians outside the U.S. have criticized Trump's annexation comments. The Democratic Party has introduced bills to prevent the Trump administration from invading countries without the approval of Congress.

Background

The last territory acquired by the United States came in 1947 with the acquisition of the Northern Mariana Islands, Caroline, and Marshall Islands. Of these islands, only the Northern Mariana Islands would become a U.S. territory, with the others becoming independent in the 1980s and 1990s under Compacts of Free Association.

During both of his presidencies, U.S. president Donald Trump expressed a desire to expand the United States' territory through both land purchases and military means. Multiple authors have observed that Trump's imperialist and expansionist mentalities had intensified in 2026 as proven by patterns of increased aggression against multiple countries.

Trump's determination to treat the Western Hemisphere as a U.S. sphere of influence has been characterized as a revival of the Monroe Doctrine. The 2025 National Security Strategy announced the "Trump Corollary" to the Monroe Doctrine, also known as the Donroe Doctrine. Secretary of State Marco Rubio claimed that the European Union has no right to define how the United States can operate its national security and that Trump is responding to defend their country. Deputy Chief of Staff Stephen Miller explained the administration's foreign policy by invoking the country's position as a superpower: "We're a superpower. And under President Trump, we are going to conduct ourselves as a superpower." According to a February 2025 poll by YouGov, only 4% of Americans support American expansion if it requires force, 33% of Americans support expansion without the use of force, and 48% of Americans oppose expansion altogether.
