The Sovereignty of the United States was never at risk in World War II
We were told at the time we were fighting Facist Totalitarianism. and that is the same thing we are being told that we will be fighting now.
Only after World War II was it clear that the German and Japanese were engaged in crimes against Humanity.
The difference this time is that we know about Sadam's Crimes against Humanity in advance or our action to rid the world of his menace.
Using your locig, you would have been against World War II. You only support the Action in World War II based on hindsight of the attrocities committed by Hitler.
