I invite the fat yanks to just try. The whole population of Canada (those that weren’t instant killed in the first air assault) would instantly self-deputize into guerilla savagery. You don’t know the Canadian ethos. Millions of allied Americans would join us too from the inside.
If even 1% of Canadians became insurgent (many more would) that would be more than enough to fuck shit up for any US invasion.
The US has never fared well with insurgent groups protecting their homeland, case in point: Vietnam, Afghanistan, the Korean War.
