Obama_Raises_Specter_Of_War-e8ec7542f0ce2c4c3a96e7a0b99d0cb4President Barack Obama strongly warned Congress on Friday against leveling additional sanctions against Iran and even suggested they could lead to war. “We have shown that we are credibly trying to solve this problem and avert some sort of military showdown. In that context, t here is no good argument for us to — undercut — undermine, the negotiations,” Obama said. The White House and Iran are currently locked in negotiations for Iran to roll back its nuclear program in exchange for the US and others lifting their sanctions against the Iranian government. These negotiations have been repeatedly extended and frustrated members of Congress said they fear Obama will not strike a tough enough deal. Even Democrats have backed legislation to strengthen the sanctions against Iran. Speaking at a joint press conference with British Prime Minister David Cameron, Obama said such legislation would likely result in the negotiations collapsing. He argued Iran could easily return to building a military-grade nuclear reactor — setting the stage for an aggressive showdown. “They would be able to maintain that the reason that they ended negotiations was because the United States was operating in bad faith and blew up the deal,” he said. ” The likelihood [that] the entire negotiations collapses is very high. And if that happens, there is no constraint on Iran at that point going back and doing exactly what it had been doing before: … developing a heavy water reactor, that once built is extraordinarily difficult to dismantle.” More
