You do not get to decide that. If we allow everyone to invade other countries and murder leaders because they deem those people worse than themselves, the world will be engaged in endless war. Or do you think perhaps deciding who to invade and kill is a special privilege reserved only for your country, which should be emperor of the world?
The preceding comment was about holding someone responsible. It appears you might have misunderstood that mine points out that this is exactly how the school was hit.
I also don't even know what you're getting at. There was nothing "relativistic" or "morally grey" about my argument. My point is that in order for any kind of peace to exist, each country must be able to accept that there will be other people in the world who are morally repugnant to them. Because there will always be leaders who consider each other repugnant, so if you endorse starting wars over that, you're committing to a world where everyone is starting wars all the time as the international norm.
