Throughout the last year former Middle East peace processor and Obama foreign policy staffer Dennis Ross has been sounding a note of caution about the nuclear talks with Iran. But after sober reflection, the veteran diplomat is endorsing the weak nuclear deal that has yet to be put to paper. But despite Ross’s optimism about the agreement’s ability to forestall Iran from getting a bomb for as much as 25 years, even he admits that the statements coming out of Tehran about the final written terms of the pact are troubling. Ross concedes Iran’s attitude can, in fact, render the framework a colossal failure if Western negotiators don’t stick to positions demanding transparency about their nuclear program. That’s true enough though why anyone would think President Obama would stand firm with the Iranians now it meant risking a deal he considers integral to his legacy is a mystery. That’s especially true after making concession after concession in order to get the deal. But scholar Michael Mandelbaum has an even better reason why this mess can’t be salvaged. As he explains in an article published in The American Interest, the problem here isn’t just bad negotiating tactics but a fundamental reordering of American foreign policy by Obama that undermines its credibility in enforcing agreements and restraining rogue regimes.
