Bush never tried to invade Iran, there was talk of it but we were to involved in Afghanistan and Iraq, the U.S. military is not that big. As President Bush could have attacked Iran just as he attacked Iraq. Officially, the War Powers Resolution requires the president to provide written notification to Congress of the introduction of U.S. armed forces into hostilities within forty-eight hours of such action. The president must explain the reasons forces were inserted in a hostile situation, the executive's authority for doing so, and the scope and duration of the military action. In addition, the president is required to terminate the use of military forces after sixty days unless Congress has declared war. Democrats had nothing to do with the decision no matter what credit they try and take,as I mentioned we would have been spread dangerously thin if we had.
