Prime Minister Benjamin Netanyahu unveiled a massive cache of secret documents, obtained in an exceptional Israeli intelligence operation this year, showing that Iran had developed a secret nuclear weapons program and that it lied when it claimed otherwise.“Iran lied big time,” Netanyahu said at a dramatic press conference on Monday night in Tel Aviv that involved props and a slide show.Netanyahu held a microphone and walked back and forth on the stage as if conducting a class.To catch international attention, Netanyahu spoke in English as he described a massive Israeli intelligence coup by which some 100,000 documents – weighing around half a ton – were brought from Tehran to the Jewish state.“In 2017, Iran moved its nuclear-weapons files to the Shorabad district in southern Tehran. Few Iranians knew where it was, very few, and also a few Israelis,” Netanyahu said. “From the outside the vault looked like a dilapidated warehouse. It contained Iran’s secret atomic archives locked in massive files.”“A few weeks ago, in a great intelligence achievement, Israel obtained half a ton of the material inside these vaults,” Netanyahu said. He explained that these included 55,000 pages of documents and another 55,000 files on 183 CDs.The documents focused on the secret Iranian nuclear program that was developed from 1999 to 2003 called Project Amad. When Iran entered the 2015 nuclear deal, it denied that such a program existed.Netanyahu made the presentation as part of his continued campaign against the deal. He said the documents proved that the deal itself was based on falsehoods and that Iran continued with its nuclear program after the deal was signed.He spoke less than two weeks before the May 12 deadline that US President Donald Trump had set to decide whether or not to scrap the deal, which the US signed along with five other world powers: Russia, Germany, China, the UK and France. Meanwhile, the Knesset gave the power to declare war to the security cabinet, instead of the wider cabinet. Netanyahu and Justice Minister Ayelet Shaked have been pushing for the passage of the bill.IN WASHINGTON, Trump lauded Netanyahu’s presentation.“I don’t know if everybody has seen it, but I got to see a little bit of it, and that is just not an acceptable situation,” he said, referring to the nuclear deal.“So we’ll see what happens, Trump said. “I’m not telling you what I’m doing. But a lot of people think they know, and on or before the 12th we’ll make a decision. That doesn’t mean we won’t negotiate a real agreement. It’s a horrible agreement for the US.”Israel had known for years that Iran had a secret nuclear weapons program from 1999 to 2003 called Project Amad, Netanyahu said. “We can now prove that Project Amad was a comprehensive program to design, build and test nuclear weapons,” Netanyahu said. “Iran is secretly storing Project Amad material to use at a time of its choice to develop nuclear weapons.”The project’s mission statement was to “design, product and test five warheads, each with 10-kiloton TNT yield for integration on a missile. You do not have to read Farsi to see ‘10 kiloton’ here,” he said.“That is like five Hiroshima bombs to be put on ballistic missiles,” Netanyahu said.He showed a spread sheet that spoke of yellowcake production, centrifuge enrichment process, warhead project, simulation project and tests.“Project Amad had the five key elements of a nuclear weapons program,” said Netanyahu.This included designs for enriched uranium as well as the development of nuclear cores and photographs of a secret underground facility to produce these cores.Israel found photographs of a system to build a nuclear implosion system and a map with five key testing sites in eastern Iran, Netanyahu said.“We have many more such documents,” said Netanyahu.There were also documents that showed how to integrate nuclear warheads on missiles, including for Shahab-3 missiles.“Here is the warhead, here is the bomb,” said Netanyahu, pointing to different points on a diagram.Iran is continually expanding the range of its nuclear-capable missiles and can reach Riyadh, Tel Aviv and Moscow.“But they are working on far greater ranges,” he said.“These files conclusively prove that Iran is brazenly lying when it said it never had a nuclear weapons program,” Netanyahu said.In 2003, Iran was forced to shelve Project Amad, but not its nuclear ambitions. It split its program into an overt program and a covert one that continued the nuclear work under the title of scientific knowhow development, Netanyahu said.It continued this work in a series of organizations and in 2018 it is carried out by SPND, an organization inside Iran’s Defense Ministry led by the same person who led Project Amad – Dr. Mohsen Fakhrizadeh, Netanyahu said.Many of SPND’s key personnel worked with Fakhrizadeh on Project Amad, Netanyahu said.The files Israel uncovered also dealt with the Fordow uranium enrichment facility, which Netanyahu said was designed from the start to be part of Project Amad.“You will not be surprised that Iran insisted on keeping Fordow and the nuclear deal enabled it to do it. But Iran was required by the International Atomic Energy Agency to come clean about its nuclear program.“This was an explicit condition for implementing the nuclear deal. In December 2015 the IAEA published its final assessment of the military aspects of Iran’s nuclear program. This was Iran’s chance to fully come clean to the IAEA. They could tell the truth,” Netanyahu said.But instead, Iran denied the existence of a coordinated program and specifically denied the existence of the Amad plan, Netanyahu said.He also showed photographic evidence that Iran conducted metallurgical work specifically designed for a nuclear device.“This is just a fraction of the total material that we have,” Netanyahu said.One has to ask, he said, “Why would a terrorist regime hide and meticulously catalogue its secret files if not to use it at a later date?”“Iran lied about never having a nuclear weapons program, it continued to preserve and expand its nuclear weapons knowhow for future use,” Netanyahu said.He played a tape of Iranian Foreign Minister Mohammad Javad Zarif stating that Iran had never had a nuclear weapons program.“Yes you did,” Netanyahu said. “And the atomic archive proves it.”“In a few days’ time, Trump will make a decision of what to do with the nuclear deal. I am sure he will do the right thing for the US, for Israel and for the peace of the world,” he said.FOR HIS PART, the US president acknowledged growing expectations that he will pull out of the accord by May 12. If the European powers fail to come up with “substantial” fixes to some of the agreement’s most controversial provisions, Trump says he will allow for nuclear sanctions to snap back into place, effectively withdrawing the US from the 2015 agreement by default.Trump said scrapping the non-proliferation agreement would send “the right message” to North Korea in upcoming negotiations over its own nuclear work, given “new information” that had come to light on Monday.But if Trump is indeed preparing for a withdrawal next month, not all of his cabinet members are yet on board. Asked on Monday after Netanyahu’s speech whether he is satisfied the JCPOA can handle incidents of Iranian cheating, James Mattis, the US defense secretary, said “yes.”Mattis met with his Israeli counterpart, Avigdor Liberman, last week in Washington, primarily on Iran policy, the two departments said.The president also claimed the current deal “frees” Iran to develop nuclear weapons in seven years. The letter of the agreement commits Iran never to construct nuclear weapons – a pledge it originally made in joining the Nuclear Nonproliferation Treaty in the 1970s. But Netanyahu’s point was that Iran’s commitments were based on lies, raising questions over whether their weapons program had ever ceased and over what sort of agreement with Iran would ever be considered of good faith.The deal, formally known as the Joint Comprehensive Plan of Action, put caps on Tehran’s enrichment of uranium that phase out between 10 and 15 years. As those “sunset clauses” are reached, Iran will be allowed to grow the size and efficiency of its program, installing advanced models of uranium-enriching centrifuges in place of decades-old technology, in greater numbers and at more facilities.That will shrink the “breakout time” Iran would need to develop fissile material for nuclear bombs, should it make the political decision to proceed.Trump wants a deal that will grant UN inspectors snap access to Iran’s military facilities, where much of their past nuclear weapons work took place; an end to their program on ballistic missiles, designed to deliver nuclear warheads; a permanent extension of the “sunset clauses”; and commitments from world powers to thwart Iran’s military ambitions across the Middle East.NETANYAHU RECEIVED praise from coalition and opposition politicians after his presentation of Iran’s nuclear violations. Deputy Minister Michael Oren (Kulanu) said Netanyahu presented impressive intelligence accomplishments for Israel. He said the international community must demand unlimited oversight over Iran’s nuclear program, including in closed military sites and prevent the development of Iranian ballistic missiles. Former defense minister Amir Peretz (Zionist Union) said the evidence Netanyahu presented proved that Iran is obsessively seeking nuclear weapons. He said Israel must demand more inspections of Iran’s nuclear sites, the maintenance of Israel’s qualitative military edge, and immediately work to fix security flaws in the Israeli home front. But Joint List MK Dov Henin called Netanyahu’s presentation an election speech.“What were all of those empty binders, disks and English for?” Henin asked. “He merely warmed old noodles that were cooked years before the nuclear deal was signed. A leader facing corruption charges was trying to persuade another leader facing corruption charges to inflame a conflagration whose price would be paid by the people who live here.” Iran’s foreign minister said Israel’s accusations were “old allegations” that had been dealt with by the United Nations nuclear watchdog in the past.“Pres. Trump is jumping on a rehash of old allegations already dealt with by the IAEA to “nix” the deal. How convenient. Coordinated timing of alleged intelligence revelations by the boy who cries wolf just days before May 12. But Trump’s impetuousness to celebrate blew the cover,” Zarif tweeted.Iranian state TV said Netanyahu’s accusations were propaganda.“His remarks were not new... full of baseless accusations... and propaganda against Iran’s nuclear work,” state TV said.Netanyahu spoke to Trump by telephone on Sunday and met in Tel Aviv with US Secretary of State Mike Pompeo. Prior to the presentation, the security cabinet met.On Monday, he spoke with French President Emmanuel Macron and German Chancellor Angela Merkel about the cache of documents and promised to send professional teams to their countries to explain the material. Netanyahu also held a conversation with Russian President Vladimir Putin and he plans to update the British and Chinese leaders as soon as possible.Over on Capitol Hill, response to the presentation was muted. Senator Bob Corker, the Republican from Tennessee who serves as chairman of the Senate Foreign Relations Committee and who drafted the 2015 law that provides Congress with review powers over the nuclear deal, said Netanyahu revealed “nothing new” that was not known prior to the conclusion of the agreement.Gil Hoffman and Reuters contributed to this report.
