WASHINGTON http://www.newyorkrangersteamstore.com/adidas-tie-domi-jersey , Aug. 5 (Xinhua) -- U.S. President Barack Obama on Wednesday made an all-out effort to defend the Iran nuclear deal, warning that blocking the accord by Congress would lead to war in the Middle East.


"Congressional rejection of this deal leaves any U.S. administration that is absolutely committed to preventing Iran from getting a nuclear weapon with one option, another war in the Middle East," Obama said in a speech at the American University. " The choice we face is ultimately between diplomacy or some form of war."


He added that he has not shied away from using force when necessary, warning that "if Iran does not abide by this deal, it's possible that we don't have an alternative."


The President also warned that by killing this deal, Congress would accelerate Iran's pathway to a bomb.
