what was exposed is that Bush's policies failed because it was an ill-conceived plan. It produced little or no result. Osama bin Laden slipped thru and got into Pakistan. That was the result.
Now with Obama - he fixed Bush's mess, got Pakistan to cooperate with us, and maybe kissed some ass here and there but hey - that's what diplomacy is all about! so that our men (SEALs, CIA, etc.) can do their job. Previously, Pakistan refused to cooperate with us under Bush Administration. Now with Pakistan's cooperation and others, we got him! D-E-D! DEAD!
