Some liberals already tried to claim that Congress hadn't specifically declared war but lost in court because a couple of days after the election, they DID autorize the president to use military action agains Iraq.**********************
Congress is responsible for deciding war.
The "Authorization of Force" did not decide war, it delegated to the Executive Branch the power to decide if we were going to war OR NOT.
"Yes or No" is the rightful decision of Congress, not of the President.
