John Kerry's Impeccable Timing Strikes Again

Emphasizing that a nuclear-armed Iran would be "a very serious threat to the U.S. and our allies," Kerry contended that the most conservative estimates are that Tehran is at least five years away from developing atomic weapons.

"There is time for diplomacy to work here," he said, but added that negotiating with Iran is "an uncertain proposition at best."

Kerry spoke before news broke of the agreement between six major powers, including the U.S., to offer an incentive package for Iran to abandon its nuclear ambitions. He hailed Secretary of State Condoleezza Rice's recent offer of direct negotiations with Iran, but said any talks "must be more than an effort to check the box on diplomacy as they move toward a confrontation."
