"We live in a different world, sustained not merely or even necessarily by the ability to enforce our wishes, but actual moral principles of state-to-state behaviour"
I wish you were right here, but in my opinion it's sadly obvious you aren't. The rest of your comment is quite on spot, though I wouldn't consider some of the moral justifications too overwhelming. E.g. 'Granada invasion', 'Panama invasion', and 'Contra' .
