Iran agree the nuclear freeze for ten years.
Iran should agree to freeze its nuclear activity for at least a decade if a landmark deal is to be finally reached, US President Barack Obama has said.
Mr Obama also said the odds were still against such an agreement happening.
Israeli Prime Minister Benjamin Netanyahu is expected to oppose a deal in a speech to Congress on Tuesday.
But the president said Mr Netanyahu had been wrong on Iran before, when he opposed an interim agreement last year.
"Netanyahu made all sorts of claims - this was going to be a terrible deal, this was going to result in Iran getting $50bn worth of relief, Iran would not abide by the agreement."
None of that has come true, Mr Obama said.
"During this period we've seen Iran not advance its program me. In many ways, it's rolled back elements of its program me."
Such differences of opinion between the US and Israel would not be "permanently destructive" to relations between the two countries, he added.
Mr Netanyahu was invited to speak at the US Capitol by Republican House Speaker John Boehner, a move that angered Democrats.
