I've lost count of how many bills republicans have thrown at Obama to undermine our successful negotiations. Reinstating sanctions means Iran reinstating their nuclear program! If we don't hold up to our side of the deal, neither will they. This is a perfect way to ensure our relations sour not only with Iran, but with Europe, China, Russia, and all other co-sponsors of the nuclear deal. We have successfully prevented Iran from acquiring nuclear weapons without having to yet again increase military expenditure and risk power vacuum from the air strikes Republicans wanted to implement, so this bill reflects their party putting their partisanry before U.S. foreign interest. Trump himself has walked back on calls saying he would rip up the nuclear deal, saying he will now instead build upon it after meeting with foreign policy professionals in Washington. It's amazing what professionalism can do for responsible policy.
