Israel's prime minister is praising President Donald Trump's address to the United Nations that condemned Iran.
He said Trump is looking at the entire situation in Iran, not just its nuclear program, when deciding on the deal.
Mohammad Golshan, who was born in Iran but has lived in Toronto for three decades, said his belief is that the American administration "should not deal with the Iranian government".
Secretary of State Rex Tillerson emphasized Wednesday that the USA is asking its allies to factor Iran's broader activities, not just its nuclear program, in considering additional sanctions against the longtime U.S. foe.
It was not clear whether renewed discussion about extending the deal will be enough to convince Trump to endorse the accord before he is due to report to the US Congress on October 15 to certify Iran's compliance.
Trump's meeting with Netanyahu was the first of the many world leader confabs he is scheduled to have on the sidelines of the United Nations General Assembly this week.
Iran and the five permanent members of the UN Security Council - the United States, France, Britain, Russia and China - plus Germany signed the nuclear agreement on July 14, 2015 and started implementing it on January 16, 2016. "We're talking about it constantly, so you'll see".
"We do need the support of our allies, our European allies and others, to make the case as well to Iran that this deal really needs to be revisited", Tillerson told the Fox News television channel.
"They were told clearly and definitively (by us) that the nuclear deal can not be renegotiated", he told a press conference in Tehran broadcast live on state television after his return from the U.N. General Assembly. On Wednesday, he said " I have decided " whether the USA will continue to abide by the deal, but declined to elaborate.
The leaders gathered at the JCPOA meeting had an "open and candid exchange", Tillerson said.
"It will be a great pity if this agreement were to be destroyed by rogue newcomers to the world of politics: the world will have lost a great opportunity", Rouhani said, adding that Iran was a moderate country dedicated to maintaining peace.
The rhetorical threats have anxious the other countries in the agreement: Britain, China, France, Germany and Russian Federation.
He added: "I know what the decision is but when the President reveals that, when he talks about it, he'll place it context of the broader approach to Iran".
Given the current situation, holding talks with the USA "would be a waste of time", the Iranian president added. "And then the incompleteness of the deal. which really could give the regime cover to advance a nuclear program". If he does not, the U.S.
"I couldn't agree more", Netanyahu said from the same podium several hours later.
"An American government that chooses to trample on her legal and legitimate global commitments, a conversation with such a government would be a waste of time", he said.
