Bush did not start the Afghanistan war that was started by Bin Laden officially on 9-11-2001 but in reality it had been going on before Bush ever came into office with the first WTC attack, the attack on the U.S.S. Cole, and embassy bombings in Kenya and Tanzania it took the 2001 attack for the nation to finally wake up and realize war had been declared on us. While the Iraq war was a mistake we did have Iraq in a position to have a good chance of being a stable democracy by the time Bush left office but the Obama administration could not work out a status of forces extension agreement and all our troops were pulled out creating a power vacuum which has been filled by Al-Qaeda returning and radicals being backed by Iran. It's fair to criticize the Bush administration for the Iraq decision but that decision does not make sitting on the sideline and taking a almost isolationist tone to international problems a wise one.
