One of the major lessons of the 1900s is that the moral ills of your own tribe are more important than the problems other people might have. You don't live in some other country, you live in your own. Local concerns are by far the #1 issue.

Even in the 2000s, one of the most ironic outcomes is that US hegemony forced a bunch of countries into really dominant regional positions (thinking especially of Japan, China and Germany) because they had nothing else to do but fix their own internal problems and it turns out that is a dominant strategy over militarism. Moral positions like peace, law, consistency and fairness aren't vague nice-to-haves, they are principles that lead to better outcomes for the people who stick with them.
