We should never again go to war without a draft and a declaration of war from Congress. As it is, the nation is not really at war. Only the military is at war. The rest of us are sitting back and either watching, or simply ignoring, what is going on, while soldiers are sent back for tour after tour of combat duty. It's unfair.
When the president declared unconstitutional war in the '60s, the nation was at war due to the draft. That war was real to the people who faced the draft themselves, or whose sons faced the draft. The next unconstitutional undeclared war, there was no draft and the entire burden of it fell on the soldiers. The result? No real protests, no real involvement by most of us.
When we go to war, the whole country should be at war, like we were in WWII, or we shouldn't go to war. It's really that simple.
