If Quebec goes independent, join the BRICs, and goes into a military alliance with Russia and China, and lets China and Russia build military bases, we would hear a whole different story from US NeoCons of the “sanctity of international borders” and the “independence of sovereign states” ... etc. etc.
A positively SILLY speculation. Quebec is too dependent on the rest of Canada to actually declare independence. The last "independence" flurry caused a huge outflow of industries to Ontario and the Maritimes, leaving them almost without an industrial economy. They won't do that again.
We went to war with Germany over a telegram suggesting that Mexico join the Central Powers. It didn’t matter if the Mexicans accepted the offer or not.
