But not everyone is sure that President-elect Donald Trump’s talk of annexing Canada and Greenland and reclaiming the Panama Canal is driven by a deeper strategy.

President-elect Trump has spent parts of the holiday season vowing to take over the Panama Canal, calling for the U.S. to buy Greenland from Denmark and suggesting Canada could become the 51st state.

In recent days the president-elect has called for asserting U.S. control over the Panama Canal and Greenland, showing that his “America First” philosophy has an expansionist dimension.
