I remember having very mixed feelings. I felt Afghanistan was in some sense justified, though perhaps a Very Bad Idea. (The whole, "Afghanistan breaks empires" history lesson.) For Iraq, I thought they probably did have a WMD program, but still thought it was a Very Bad Idea.

I did feel that the War on Terror was a terrible way to frame the conflicts, and could see (as did many) that doing it that way meant there would never be any kind of obvious end-point. But I figured they would have some plan to prop up Afgh/Iraq after the main battles were won.
So I was indeed surprised to find that they had exactly no plan for stabilizing the region. And I am continually appalled that we have not found a way out of these conflicts. And yes, I think the overall bloodshed is disgusting, appalling, immoral. For what it is worth.
