Joe Biden promised Europe that "America is back" early in his presidency, aiming to mend ties after Donald Trump's tenure. However, nearly five years later, Trump's influence over Europe has grown. Recently, Trump demanded Denmark cede Greenland to the U.S., causing turmoil within NATO. European leaders are responding by exploring alliances that exclude the U.S. Canadian Prime Minister Mark Carney highlighted a global shift, calling the rules-based order an "illusion." European leaders criticized Trump's approach, while some Republicans supported him. Democrats urged stronger responses, stressing the need for a lasting shift in U.S. politics to rebuild trust.
