Don’t get me wrong, I am passionate about civil and economic rights in Quebec. But I accept that certain rules change at the Vermont border. The question even the most ardent internationalist must ask is at what threshold do things in another jurisdiction become so intolerable that they would need to get personally involved and intervene in another People’s business. In international law, which we can take as the base rate, that threshold is pretty high, at crimes against humanity-ish. From there it goes down. How far down? Depends on the balance different communities are willing to strike. Inter-community intervention also has its own catastrophic consequences. There is no right answer of course but I strongly suspect the contemporary American one is not it.
