If only that was all he did.  The first Gulf War:  He told the opposition within Iraq -against Saddam Hussein, to rebel from inside, and the US would support them.
After the US had driven Hussein's army out of Kuwait into Iraq, he stopped the advance, reneged on his promise, allowed Hussein freedom to fly again within Iraq, where Hussein promptly bombed and executed all the rebels.  
Bush also allowed the use of plutonium-tipped anti-tank shells that cut through tanks' steel like soft butter (plutonium is 50% denser than lead).  Its also radioactive: On impact the radioactive material was aerosolized into fine dust that gave everyone, including our own troops, doctors and nurses, cancer.  Our militaries denied this 'Gulf War Syndrome' and gave no help to the victims.  Citizens around the former battle zone had children born with cancer and stopped having children.  Thanks George.  Yes and for your brain-injured son who started a 2nd war in Iraq using a lie.
