??? Do most of your everyday life decisions involve starting wars or killing people? That's concerning. Are you a high-ranking officer in the US military? As it happens, I'm not, and my decisions do not typically have life-or-death consequences.
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.
I didn't think the point was that subtle. There is good and evil, right and wrong, survival and destruction. You seem to think that drawing a line around some land and calling yourself a country immunizes you from the moral scrutiny of your neighbors.
While this certainly accords with the promulgations of the morally bankrupt UN, it is not a recipe for existing in our world. This is why it is important to have a powerful military.
But if you're getting attacked for 4 decades by another country, do you do something about it or are you saying that's also wrong?
My understanding is that the regime in Iran has been terrorizing around the world for decades. It's not just disagreeable. People are seeking justice.
It's one thing to dislike another politician. No one needs justice for repugnancy. But if they are committing acts of terror, that's a totally different thing.
