Summary

Donald Trump, previously committed to an “America First” foreign policy, has embraced an imperialist agenda in his second term.

He’s proposed Greenland’s annexation, pressuring Canada to join the U.S. as its 51st state, and threatening Panama Canal control.

Critics, including former allies, warn these actions undermine U.S. alliances, embolden adversaries like Russia and China, and disrupt global norms on sovereignty.

While supporters claim these moves address national security, allies such as Canada and Denmark have condemned the rhetoric, with experts warning of potential NATO conflicts and diplomatic fallout.
