Iraq attacks and takes over Kuwait. And then threatens to invade Saudi Arabia. But US the the 'aggressor' for rolling this back? And the US gets many allies and works through the UN to do this, but it is somehow 'illegal'? It sounds like in your perfect world, Saddam keeps Kuwait, also gets Saudi Arabia, and the US just sits on its hands after terrorists kill thousands in NYC because being 'aggressive' is always bad no matter what.
