Foreign policy of the second Trump administration

The foreign policy of the second Trump administration is an example of a realist "America First" foreign policy. It has been called imperialist, expansionist, and interventionist in respect to the Americas and Middle East, but also isolationist in respect to Europe and Africa. Trump has used the expansive version of the Monroe Doctrine, that Donald Trump himself called the "Donroe Doctrine." His foreign policy has been compared to the policy of former president William McKinley. Trump's deputy chief of staff, Stephen Miller, explained their policy saying: "We're a superpower. And under President Trump, we are going to conduct ourselves as a superpower."

The foreign policy of the Trump administration has been described as breaking the post-1945 rules-based liberal international order and as an abandonment of multilateralism. It involved dismantling or withdrawing support for both domestic and international institutions working to strengthen the American soft power, and favoring instead hard power. The moves were described as undermining American global leadership and creating a power vacuum for Russia and China. Trump's relations with U.S. allies have been transactional and spanned from indifference to animosity, while he has sought friendly relationships with some U.S. adversaries. The actions saw large drops in global public opinion of the US.

Trump initiated a trade war with Canada and Mexico and continued the ongoing trade war with China. He has repeatedly expressed his wish to annex Canada, Greenland, and the Panama Canal. He has taken a pro-Israel stance and increased support for Israel in the Gaza war. In response to the Gaza war, he proposed taking over the Gaza Strip, forcibly relocatingits people to other Arab countries such as Jordan and Egypt, and turning it into a special economic zone. In Latin America, Trump authorized a series of strikes on alleged drug traffickers, the legality of which is widely disputed under both U.S. and international law, and subsequently ordered a military operation to capture Nicolás Maduro, the disputed president of Venezuela. Following the raid, Venezuela has been described as a de factopuppet state of the U.S. In 2026, he launched a major war on Iran with Israel with the stated goal of regime change which lead to the assassination of Supreme Leader Ali Khamenei. Trump has sought realignment with Russian president Vladimir Putin, a longtime US adversary. To end the Russian invasion of Ukraine, Trump's administration offered concessions to Russia; it also said that Ukraine was partly responsible for the invasion. These moves have been criticized by most US allies and by many international institutions.
