Look, Bush screwed up on some things. He took us to war under false pretenses. However, Congress approved - he should not shoulder all of the blame (which he has not even tried to deflect). He appointed officials who did not look out for us economically - but then, Congress didn't look out for us, either. But of course everyone knows Bush...the (Democratic) leaders of Congress are significantly less well-known.
Of course I'm not going to change anyone's minds, most likely. Most of my friends and people I discourse with regularly are either part of the choir or are almost diametrically opposed to my views. But that's not to say that everything is black and white.
It's a harsh reality, but prevention and preemption are not looked upon too kindly by many people, it seems. Now I don't believe it is warranted in all cases, but Iraq was one in which it was, in my mind. For those who don't like Israel and think they are tyrants or meanies, I'm sure this means little...but I agree with Peres: http://www.ynetnews.com/articles/0,7340,L-3658858,00.html
