re the post above:
All presidents/heads of state have their fair share of problems/good-bad luck. You only have to look at Tony Blair here in Uk who has taken us to war more times than any post war prime minister, as an example of foreign policy problems.
As for President Bush, you do wonder wether he has any input at all in decisions or wether he is just a master delegator/consensus builder, with the 'key levers' of dick cheyney, rumsfeld, andrew card (chief of staff) condaleeza rice and to an extent colin powell forming the inner circle.
You don't have to look very far back to see other unlucky presidents, Carter springs to mind, but I think the difference between most presidents to judge is wetrher their luck (good or bad) is self induced. Certainly reagan, bush and clinton's 'bad'l uck was probably self induced, not so sure about carter.
