Iraq war based on the lie of weapons of mass destruction coupled with its ditching of the Geneva Convention: the US looses its world standing in moral authority. Strike one!
Hurricane Katrina recovery: the US loses its world standing as capital of "can-do" and organization—displays third-world level ineptness. Couldn't get the job done or didn't give a damn—pick one. Strike two!
Collapse of US financial infrastructure: US loses its world standing as bastion of capitalism as most of its financial infrastructure is nationalized. Strike three!
Three strikes and you're out, right? Well, apparently not in the case of the Republican Party. What other leader in the western world could survive three such massive disasters. Yet, in the US, they are seriously contemplating another Republican president. Go figure.
Think George bush has been a disaster? Wait until that old dodderer, John McCain, gets his shaky hands on the tiller of the good ship USA.
