The only positive thing about his Presidency was how he handled the US response after 9/11. I think he just turned over the US response to the military unlike LBJ sitting in the White House and trying to run the Viet Nam war and failing. Other than that the Bush global governance tribe sucks.
When he announced he wanted to go into IRAQ his minions went around saying they had super secret intel .. intel they couldn't share with us .. that proved Saddam had WMDs and intent to give them to terrorists. He asked us to go to war on the basis of having to trust him.
At that time I questioned (here!) whether it was right to go into Iraq and I decided to go along with it. My reasoning was that Bush either had irrefutable evidence he said he did (in which case it was important to stop that) or he didn't (in which case he was an evil SOB telling lies so he could kill people he didn't like at the cost of lots of American lives) and I didn't think he was evil.
It took a while but I found out I was wrong.
