Diplomats around the world are concerned about President Trump's threats regarding the Panama Canal and Greenland. Trump's administration is being closely watched to see how they will act on these threats. The world is becoming increasingly unsettled as larger nations develop plans to counter Trump's punitive tariffs and smaller countries hope to avoid further years of America First policies. Trump's focus on territorial control and protectionism mirrors the late 19th-century era of American imperialism. However, many countries are tired of the America that Trump wants to make great again, as the United States has less leverage and influence than in previous decades. The world is currently facing various challenges, including wars, autocratic partnerships, climate change, and artificial intelligence. Historians warn that Trump's attempts to calm and simplify the world through territorial expansion could have dangerous consequences.
