This is somewhat AP Stuck on Stupid. Of course the invasion is his responsibility since he's the only person that can give authorization for invasion. AP, It's called The President of The United States for a reason. Who else would have sent us, the Hollywood Bareback Mountain Cowboys?
So, we're in a dictatorship now? The part of the Constitution that talks about Congress declaring war was repealed?
Re Pres. Bush taking responsibility for Iraq, I thought only Congress had the power to "give authorization for invasion." From Section 8 of the Constitution, the following are among the powers reserved to Congress:
"To declare War, grant Letters of Marque and Reprisal, and make Rules concerning Captures on Land and Water;
"To raise and support Armies, ...;
"To provide and maintain a Navy;
"To make Rules for the Government and Regulation of the land and naval Forces;
"To provide for calling forth the Militia to execute the Laws of the Union, suppress Insurrections and repel Invasions;. . . ."
