Yes, I think Hillary would overreact militarily if she were president, and I have been thinking so for quite some time now. I think she would be quite an aggressive politician in that respect...partly from fear of being seen as weak...partly because she brooks no opposition (or perceived opposition)...at home or abroad. Nor is she inclined to admit to any mistakes, as you noted, Ron. Sounds a lot like George Bush, in that respect doesn't it?
My guess is that she and her corporate backers have no intention of withdrawing from Iraq, but are planning to stay there for a long, long time. Why? In order to manage the oil, and in order to maintain permanent military bases there in readiness for any possible future actions against Iran and/or Syria.
Unfortunately, though, I missed the debate tonight. I had a very busy day and have not had time to watch it. I guess maybe I can find it on Youtube later.
