I know someone who served in the Canadian Armed Forces and did a tour diffusing IEDs in Afghanistan. I'm pretty sure he knows how to build one if it came to that.

Americans don't recognize that Canadians actually did go to Afghanistan. It's not just Hockey metaphors, people in Canada actually do know the tactics the US military has a difficult time dealing with. That's because our soldiers had to deal with those same tactics when fighting alongside Americans for two fucking decades. If the US decides to betray Canada they will soon be reminded that Canadians were in Afghanistan and what was learned there.
