Kerry says U.S. deserves 'benefit of the doubt' on getting Iran nuclear deal

Kerry also said he hoped that Israeli Prime Minister Benjamin Netanyahu’s planned speech to Congress on Tuesday, in which he will warn against a possible nuclear deal with Iran, does not turn into “some great political football.”

U.S. and international partners are in negotiation with Iran over curbing its nuclear program but Netanyahu has cast doubt on a possible deal and says a nuclear-armed Iran would pose an existential threat to the Jewish state. The Israeli leader was invited to speak this week by Republican congressional leaders who did not first inform President Barack Obama’s administration.

In an interview with the ABC program “This Week,” Kerry said of the Iran negotiations, “It is better to do this by diplomacy than to have to do a strategy militarily which you would have to repeat over and over again and which everybody believes ought to be after you have exhausted all the diplomatic remedies.”

Kerry added that “I can’t promise you we can” reach a nuclear deal with Iran, “but we are going to test whether or not diplomacy can prevent this weapon from being created so you don’t have to turn to additional measures including the possibility of a military confrontation.”

“Our hope is diplomacy can work. … Given our success on the interim agreement, I believe we deserve the benefit of the doubt to find out whether or not we can get a similarly good agreement with respect to the future,” he said.

Kerry did say that Netanyahu is “welcome to speak in the United States, obviously,” referring to the controversy over Israeli leader’s speech, which comes just two weeks before elections in Israel.

Signs are growing that the speech could damage Israel’s country’s broad alliance with the United States.
