But the tone has changed, with leaders now suggesting that Iran wouldn't have much incentive to remain bound to the accord if the US left with the intention to rally its allies in the region and reimpose sanctions. Netanyahu said that Israeli intelligence services had obtained 55,000 pages of Iranian documents revealing that Iran had a nuclear weapons program before signing the nuclear deal in 2015.
Iran intensified its criticism of President Donald Trump days before he decides whether to withdraw the US from the 2015 nuclear deal that lifted punishing sanctions on the Islamic Republic.
European leaders, including French President Emmanuel Macron, have been pressing Trump to strengthen rather than abandon the three-year-old deal that took more than a decade to reach.
"Iran is committed to the nuclear deal but if the USA backs off" from the accord "we won't stay either", Ali Akbar Velayati, adviser to Supreme Leader Ayatollah Ali Khamenei, was quoted by state-run Mehr news agency as saying Thursday.
The United Nations' atomic watchdog previously reported such efforts and said it has "no credible indications of activities in Iran relevant to the development of a nuclear explosive device after 2009".
In a televised presentation at the Israeli Ministry of Defense on Monday, Israeli Prime Minister Benjamin Netanyahu claimed that Iran is running a program called Project Amad that is aimed at "developing five nuclear warheads".
On Wednesday, Iranian Ambassador to the UK Hamid Baeidinejad warned Trump against walking away from the nuclear agreement.
UN Secretary-General Antonio Guterres has warned of "dangerous times" as US President Donald Trump considers whether to remain in or leave the worldwide deal that seeks to rein in Iran's nuclear weapons programme.
"We should not scrap it unless we have a good alternative", he told the BBC. "Iran lied on the front end".

The Belgium striker was involved in a challenge with Konstantinos Mavropanos and injured his foot during their 2-1 win on Sunday. And Mata was concerned about the 24-year-old being forced off, especially because of the impact he has had this season.
"I understand the concerns of some countries in relation to the Iranian influence in other countries of the region".
There is a chance Trump might choose to keep the United States in the worldwide pact under which Iran agreed to curb its nuclear programme in return for sanctions relief, in part because of "alliance maintenance" with France and to save face for French President Emmanuel Macron, who met Trump last week and urged him to stay in, the source said.
"I don't know what the USA president will decide on the 12th of May", Macron told reporters while on a visit to Australia.
A British government spokesman also expressed support for the Iran nuclear pact, saying the IAEA inspection regime "is one of the most extensive and robust [ones] in the history of worldwide nuclear accords".
Under the accord, Tehran agreed to limit its nuclear programme in return for relief from United States and other economic sanctions.
The Islamic republic has always denied it sought a nuclear weapon, insisting its atomic programme was for civilian purposes.
What has the United States said, then?
Velayati warned against any move to try to renegotiate the 2015 deal.
