Secretary of State John KerryJohn KerryCongress, Trump need a united front to face down Iran One year ago today we declared ISIS atrocities as genocide Trump’s realism toward Iran is stabilizing force for Middle East MORE on Monday said France endorsed an Iranian nuclear deal in Geneva, but Iran walked away from it.
Over the weekend, Kerry and representatives from France, Germany, Russia, Britain and China failed to reach a deal with Iran on its nuclear program.
A number of reports initially said France had been the one to reject the deal.
Kerry also addressed criticism from the Israeli government over the negotiations at Monday's news conference.
“The time to oppose it is when you see what it is, not to oppose the effort to find out what is possible,” he said.
Israeli Prime Minister Benjamin Netanyahu and other Israeli officials including President Shimon Peres have slammed the proposal in the last few days.
"We are confident that what we are doing will protect Israel more effectively," Kerry said.
