Netanyahu discussed regional issues and also updated them on the important material that he revealed regarding the Iranian nuclear archive

Prime Minister Benjamin Netanyahu spoke on Friday against the Iran deal with Prime Minister Malcolm Turnbull, Indian Prime Minister Narendra Modi and British Prime Minister Theresa May.

Netanyahu's office said he "discussed regional issues with the world leaders and also updated them on the important material that he revealed regarding the Iranian nuclear archive."

Army Radio reported that a number of teams were in Israel this weekend to learn more information about the half-ton archive Israel managed to move out of Tehran.

The 100,000 pages of documents focus on Project Amad, which was Iran's nuclear program from 1999-2003.

Netanyahu argued that Iran lied about this program when it entered the 2015 deal, describing its activities as scientific research for peaceful nuclear use.

He argued that the deal was based on lies and should be scrapped. The US has sought to amend the deal and, if it fails to do so by May 12th, it has threatened to withdraw from the agreement between Tehran and the six world powers.

Russia will stand by the Iran nuclear deal and develop closer ties with Iran if US President Donald Trump withdraws from the agreement on May 12, a senior Russian official said on Friday.

Vladimir Yermakov, Director General of the Department for Non-Proliferation and Arms Control at Russia's Foreign Ministry, told reporters that a US withdrawal from the 2015 accord known as the JCPOA did not necessarily mean the end of the deal.

"It might even be easier for us on the economic front, because we won’t have any limits on economic cooperation with Iran. We would develop bilateral relations in all areas – energy, transport, high tech, medicine," he said.

Trump, a long-time critic of the deal struck by major world powers, has threatened to pull out unless a follow-on agreement is reached to fix what he calls its "flaws."

"If the United States breaks an international agreement backed by UN Security Council resolutions, it will be the United States that should suffer the consequences. Neither Iran nor China nor Russia nor the European states should lose out," Yermakov said.

Russia would continue to uphold its obligations under the deal, if it was able to and if continuing adherence to the JCPOA was in Russia's interests. Keeping the deal alive was in the best interests of international security, he said.

Likewise, there was no reason for Iran to pull out of the deal, and it was in a strong position because it was fully meeting its obligations, said Yermakov, who was attending a nuclear non-proliferation conference in Geneva.

"It’s not in anybody’s interest that Iran goes back to the kind of development of its nuclear program that all states would be concerned about. But Iran is fully entitled to develop peaceful nuclear energy," he said.

If the United States pulled out, there was no question of discussing new UN Security Council sanctions on Iran, he added.

In fact, the United States should theoretically be sanctioned for breaking an international agreement, but that would not happen because it had a veto at the United Nations.

Yermakov said nobody could foresee what calculations Trump might make about withdrawing from the JCPOA, but the vast majority of UN states at the Geneva conference had supported a joint Russian-Chinese declaration supporting the JCPOA.

Practically all states had backed the declaration, but the United States had put pressure on its European NATO allies to persuade them not to give it their backing, Yermakov said.

"That was a great surprise for us, because what we put in our joint statement completely accorded with their national positions. There wasn’t a single word that in any way contradicted their national positions," he said.

"We explained this to our European partners and it was very difficult for them. They were under colossal pressure."
