The head of Israel\u2019s Mossad intelligence agency is \u201c100 percent certain\u201d that Iran remains committed to developing a nuclear bomb and believes the international community must change or scrap its nuclear deal with the Islamic Republic.\r\nYossi Cohen, who leads the shadowy spy agency, has been holding discussions about the Iranian nuclear program and delivered his assessment in a recent closed meeting with senior officials, according to a person who attended the meeting.\r\nCohen called the nuclear deal a \u201cterrible mistake,\u201d saying it allows Iran to keep key elements of its nuclear program intact and will remove other restraints in a few years.\r\n\u201cThen Iran will be able to enrich enough uranium for an arsenal of nuclear bombs,\u201d Cohen said, according to the meeting participant, who spoke on condition of anonymity because he was discussing a classified security matter.\r\nCohen also criticized the decision to lift sanctions on Iran, saying it has resulted in \u201csignificantly increased\u201d aggression by Iran, and noted Iran\u2019s continued development of long-range ballistic missiles.\r\n\u201cAs head of the Mossad, I am 100 percent certain that Iran has never abandoned its military nuclear vision for a single instant. This deal enables Iran to achieve that vision,\u201d Cohen said. \u201cThat is why I believe the deal must be completely changed or scrapped. The failure to do so would be a grave threat to Israel\u2019s security.\u201d\r\nCohen\u2019s comments come amid an intense international discussion about the future of the 2015 nuclear deal, in which Iran agreed to curbs and inspections on its nuclear program in exchange for relief from international sanctions.\r\nHis analysis aligns closely with that of Prime Minister Benjamin Netanyahu at a time the Israeli leader is hopeful that President Donald Trump can negotiate changes to the deal. The issue has sparked some debate inside Israel\u2019s security community, with some voices pointing to positive aspects of the deal in that it has delayed Iran\u2019s nuclear development.\r\nTrump has set a mid-May deadline for changes while also threatening to withdraw from the deal. However, it remains unclear whether a compromise can be reached, and how Iran would react.\r\nTrump\u2019s disdain for the deal has been a welcome development for Netanyahu. The Israeli leader was a leading opponent of the deal, saying it did not contain sufficient safeguards to prevent Iran from reaching the capability to develop nuclear weapons as the agreement\u2019s restrictions expire.\r\nIsrael and Iran are arch enemies, and Israel has identified Iran as its top threat, citing the nuclear program, its hostile rhetoric, support for Hezbollah and its development of long-range missiles.\r\nYet other officials, both active and former, have taken a more nuanced approach by focusing on the positive aspects of the deal.\r\nIn a recent interview, Lt. Gen. Gadi Eisenkot told the Haaretz newspaper that he knows of no violations of the nuclear deal by Iran, though he said Israel is closely watching and assuming Iran can operate secretly.\r\n\u201cIf its intentions change, we will know. Right now the agreement, with all its faults, is working and is putting off realization of the Iranian nuclear vision by 10 to 15 years,\u201d he was quoted as saying.
