Kerry threatens to quit Iran nuke talks after more delays

U.S. Secretary of State John Kerry threatened Thursday to walk away from nuclear talks as he signaled that diplomats won’t conclude an agreement over the coming hours. It was the strongest indication yet of U.S. frustration with Iran. It comes two days after President Obama promised Senate Democrats the same response to Iranian intransigence, suggesting patience for continuing the current round of discussions was running out as it headed into its 14th day. Long-standing differences persist over inspections of Iranian facilities and the Islamic republic’s research and development of advanced nuclear technology.

We can’t wait forever for the decision to be made. If the tough decisions don’t get made, we are absolutely prepared to call an end to this process.

Secretary of State John Kerry

Thursday’s latest delay for a comprehensive deal is significant. Iran is demanding prompt easing of economic penalties for nuclear concessions, and the longer it takes world powers to make good on their promises, the longer they’ll have to wait for the Iranians to scale back their nuclear program. The current round of talks has already been extended twice since it started on June 27, as has an interim nuclear accord with Iran that these negotiations are meant to finalize. The preliminary deal was due to expire on June 30, then July 7 and then Friday. It would have to be renewed a third time if the talks go beyond Friday.
