Thanks for the reasonable analysis. There aren’t enough Canadian troops to do much in the US, so the hysteria from the US Right is a bit much. And ... frankly ... if the Quebec-ers eventually vote to pull out of Canada and join France (and they will), the USA is probably going to pick up several new states in the aftermath (some of them — like the Provinces of Alberta and Manitoba — being fairly conservative, and all of them being Resource-rich). This agreement may be a precursor to that to facilitate the operations that would be called for to secure the natural resources of those orphaned Provinces (France can’t be allowed to gain access to the Yukon and all the natural resources throughout the rest of Canada).
Robert A Heinlein was right ... British Canadians are Americans who have figured out how not to pay taxes to Washington.
