Bush Gave Up On Bin Laden; Obama Got The Job Done

Let's not forget moments like this, where the self-described "Commander Guy" admits that "I don't know where he (Bin Laden) is, I just don't spend that much time on him".

More to the point, journalists like Gareth Porter have proved that capturing or killing Bin Laden was never a priority for Bush and Cheney, they had other plans.
From Gareth Porter in "The Asia Times":

"Had the Bush administration's priority been to capture or kill the al-Qaeda leadership, it would have deployed the necessary ground troops and airlift resources in the theater over a period of months before the offensive in Afghanistan began.

"You could have moved American troops along the Pakistani border before you went into Afghanistan," said Lamm. But that would have meant waiting until spring 2002 to take the offensive against the Taliban, according to Lamm.

The views of Bush's key advisers, however, ruled out any such plan from the start. During the summer of 2001 Rumsfeld refused to develop contingency plans for military action against al-Qaeda in Afghanistan, despite a National Security Presidential Directive that called for such planning, according to the 9-11 Commission report.

Rumsfeld and deputy defense secretary Paul Wolfowitz resisted such planning for Afghanistan because they were hoping that the White House would move quickly on military intervention in Iraq. According to the 9-11 Commission, at four deputies' meetings on Iraq between May 31 and July 26, 2001, Wolfowitz pushed his idea to have US troops seize all the oil fields in southern Iraq."

So there you have it; the Bush Administration never wanted Bin Laden, they played the 9-11 card to seize the oil fields in southern Iraq.
While elements of the right-wing media want to credit Bush in part for the Bin Laden hit, multiple news agencies reported that the trail for Bin Laden had "gone cold" in 2005.

Now, Obama can say "Mission Accomplished".
