"Every people deserves the right to self-determination"
Here's the thing: this isn't really true, is it? There isn't really a universal right to "self determination", if there was we'd have to acknowledge the right of those successionist yahoos who want to true some random county in Montana into AnCapistan to legalize child marriage. We recognize people should be ruled by a government that represents them, and in examples like colonialism that right is being blatantly violated, but that doesn't mean every group of 10 or more people who are unhappy with their government has some universal right to form their own little country. If we did the whole world would be a patchwork of micro-nations the size of Rhode Island.
