Is everyone forgetting we have already fought one war on our northern border? Shit happens. What if Canada went nuts and elected some narcissistic tv host that wears a diaper as a leader and they formed a cult by accident and it’s members started shooting people across the border. You would want a contingency plan in place to handle that, ya know?

I assume the US military has an invasion plan on the books for about every country on the face of the earth. They gotta spend all the trillions of dollars of black money on something.
