Canada

They don't need attack subs. They need boomer subs. At this point, Canada needs a nuclear deterrent. And I say that as an American who would be in the cross hairs of said nuclear deterrent. Canada should contract with the French for protection under their umbrella until they can build some of their own. The lesson of Ukraine should be that nukes protect small nations from fascist larger ones. Canada could easily end up like Ukraine. It's not like fascists can't find a casus belli. Putin was "restoring Russian glory" or some such. Trump would be "finishing the American Revolution" or some other bullshit.

Please, Canada, from a friend of yours to the south, do not take this threat lightly. No one is going to be able to save you if the US decides to invade. The same oceans that protect you will prevent your rescue. The only hope Canada will ever have of being able to militarily protect its borders from the US is a credible nuclear deterrent.

Just please, don't harden your hearts while you build these weapons of destruction. Don't close your doors to refugees from the US. As someone who is on the regime's enemies list, hopping across the Canadian border and begging for asylum is the last chance I might have if things really go bad.
