Mr Director is correct. NORAD is a joint operation between the two countries. It would be pretty hard for Canada to stop anything while American military personnel are standing right next to them. Tango Delta Sierra
That last comment is not even worth dignifying with a response, and it's clear you don't pay much attention to my posts.
However, I do need to walk back one item; Canada's officers are still working alongside US officers as you said. The report I saw quoting the 40% has since been deleted, so it was obviously false.
That being said, the US needs Canada for strategic defense a lot more than Canada needs the US. Most strategic targets on Canadian soil involve NORAD in some way, so they are more American targets than Canadian; they just happen to be on Canadian soil. Plus, the US has shown Canada repeatedly that they are not a reliable partner. Canadians, like Americans, also have their own political divisions, although they are not nearly as severe nor are they as obvious. However, the US has managed to rally Canadians from all points along the political spectrum and they are all pissed at the United States over recent behavior. This includes their PM.
Canada is the US's second largest trading partner, even over China, and as mentioned earlier, key allies in American strategic defense. Americans and Canadians have enjoyed almost seamless border crossings both ways for decades. The US and Canada share one of the longest unprotected international borders in the world. Now their social media is flooded with "buy Canadian" videos and memes.
Canadians fought alongside Americans in World War 1. They fought alongside Americans in World War 2. They fought alongside Americans in the Korean War. They fought alongside Americans in the Vietnam War. They were responsible for helping bring home six Americans who had evaded capture during the 1979 hostage crisis at the American embassy in Tehran. They fought alongside Americans in Iraq. They responded to the Article 5 declaration after the US was attacked on 9/11 and fought alongside Americans in Afghanistan.
Why in the name of all that's unholy would we want to antagonize them by minimizing their role in most of
America's wars - not theirs - and disrespecting Canadians who died in those wars? Can you provide me with a single valid reason why any sitting American administration should be engaging in this kind of behavior with an ally who has joined America in fighting wars for over a century? Please justify that for me. I'll wait.
