So, it seems all the reading I do is talking about America, or possible scenarios taking place in the US. Obviously, with Canada sharing a massive border, and a huge amount of trade with the US, there would have to be some sort of 'fallout' if anything were to happen in the US. Terrorist attack shuts down airports/sea ports, shipping routes, borders close... etc. But what's the impact on Canadians? Nuclear weapons used against the US... impact on Canadians (assuming no Canadian targets)? Just how far will radioactive fallout travel with prevailing winds? Perhaps I'm checking the wrong sites... all of my information seems to be US-based... but I'm Canadian, I want to know whats happening here too!
