It does somthing, i.e., it aids and abets the enemy and undermines the morale of our troops. As Kerry said in his lying 1971 testimony before Congress, "How do you ask someone to be the last man to die for a mistake." Imagine if you have a family member in combat in Iraq and you have Congress passing a resolution condenming our involvement there and pressing for withdrawal. And you have Obama stating that the loss of lives of our personnel in Iraq is a "waste." This will have far-reaching consequences on recruiting and retention of our personnel in the military, in much the same way that Vietnam had.
