" There can be absolutely no question that if the Vienna plan is fully implemented, it will make Egypt and all the countries of this region safer than they otherwise would be or were, " Kerry said in a joint press conference with his Egyptian counterpart Sameh Shoukry on Sunday.

But some restrictions will be placed on Iran’s nuclear program in exchange for the removal of sanctions against the Islamic Republic. The top US diplomat will hold meetings with his six Persian Gulf counterparts in the Qatari capital to lessen their fears about the nuclear accord. "This is an opportunity, really, for the secretary to do a deep dive with the [P]GCC foreign ministers to try to respond to any remaining questions that they might have and hopefully to satisfy them and ensure that they're supporting our effort going forward," a State Department official said. PGCC member states are Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates.
