Former Secretary of State James Baker III on the Obama administration's negotiations with Iran for a nuclear deal. He points out the importance of the U.S. making the removal of sanctions gradual manner as Iran fulfills its part of the agreement. Baker says Iran in the past has broken agreements to resume nuclear weapons research, making the verification process and snap back of sanctions critical. Baker does not address the issues related to how effective verification would take place, calling this the work of negotiators to work out the bureaucratic and cumbersome provisions. He also does not address the problems other critics have raised about any future snap back of sanctions because of the reluctance of European countries, saying only that the U.S. should maintain its credible position on the negtiations with its other partners- China, Russia, Germany, France and the UK.
