President-elect Donald Trump took aim at Canada, Greenland and the Panama Canal in a series of Christmas Day social media posts that suggested the United States could take control of all three.

President-elect Donald Trump ran on a platform of isolating the US from foreign conflicts like the Ukraine war, increasing tariffs on foreign trade partners, and rebuilding domestic manufacturing. But in recent days he has suggested a more outwardly aggressive approach for his foreign policy.

Trump named Miami-Dade County Commissioner Kevin Marino Cabrera as his choice for the post after suggesting that the US should take control of the Panama Canal – a proposal he first floated over the weekend while claiming that Panama is “ripping off” American ships that pass through the waterway.
