Imagine waking up one morning to find that the northern border no longer marks the edge of the United States. Instead, it now stretches deep into what was once an entirely separate country, and Canada has been fully integrated as the 51st state of the US. Although this sounds like something out of a speculative novel or late-night political debate, President Donald Trump has recently threatened to annex Canada and bring it into the fold of the United States. This is most certainly a far-off probability, but what would actually change if this were to happen?
The US and Canada are two of the largest countries on the planet, not only in geographic area but also in political scale. If their resources, armies, and ideologies were to merge, the entire planet would be reshaped in the aftermath.
