If the mess you're referring to is in the Middle East, you couldn't be more wrong. The Gulf war was fought with exactly the right amount of international diplomacy and overwhelming force, while leaving intact the balance of power in the region.
It was his brother Jr who destabilize by taking out Saddam in leu of bin laden, Jimmy Carter who took out the Pahlavi family in Iran and numbnuts zer0bama who took out Kadafi.
The only major mistake he made was to label Islam "A religion of 'peace'". Nothing could be further from the truth.
