thats really stretching it. I guess Bush could simply claim the Northern Alliance in Afghanistan and Kurd Iraqi were the legit government, thus the invasion don’t need Congressional approval because we were working in concert with the legit government
Bush did it the right way, the constitutional way. He got Congress to vote approval of his actions the whole step of the way. Those votes were a de jure declaration of war. The Constitution gives the power of declaring war to Congress and Congress voted twice, once in 2001 and later in 2002. Remember, a declaration of war does not have to be headed Declaration of War. It only has to give the authorization, and the ones in 2001 and 2002 did.
In case you missed it President Bush went in front of of Congress to make his case, unlike that arrogant pos occupant of 1600 Pennsylvania Ave who just went ahead to bomb Libya and or Egypt. President Bush also went in front of the UN to make his case
