He did hurt us.
He was told on August 6th 2001 by CIA, that Osama Bin Ladin was planning to planes to crash into building in US. He ignored this and went for his vacation which lasted for several weeks. He did not do anything about it.
He gave tax breaks to the rich, which took us from budget surplus to a record budget deficit. Then came the financial crisis.
He was wanted to invade Iraq long before 9/11. Iraq is not responsible for 9/11 nor did they have WMD.. He was a failure in running Iraq after the invasion.
To symbolize how the world looked at him, just watch the video clip where he had to pull a stunt to dodge shoes that came flying towards him.
