The United States concluded that Iran was violating its obligations of protection under Article III of the NPT and continued to argue, on the basis of evidence, that Iran`s weapons enrichment program was contrary to Iran`s non-proliferation obligations.  The November 2007 U.S. Secret Service estimate subsequently concluded that Iran had stopped an active nuclear weapons program in the fall of 2003 and was arrested in mid-2007. But the NIE`s “key rulings” also highlighted the fact that Iran had stopped in 2003, only “the work of designing and arming nuclear weapons and the work of converting uranium and enriching uranium undercover”, namely aspects of the Iranian nuclear effort that had not yet been disclosed to the press at that time and which were the subject of IAEA investigations.  Article III: Any non-NWS party undertakes to reach an agreement with the IAEA on the application of its safeguards to all nuclear substances in all peaceful nuclear activities of the State and to prevent the diversion of such materials to nuclear weapons or other nuclear explosive devices. In May 1998, after India`s nuclear tests earlier this month, Pakistan conducted two nuclear test groups, the Chagai-I and Chagai-II. Although there is little publicly confirmed information, it is estimated that up to 120 warheads were born in Pakistan in 2015.   According to analyses by the Carnegie Endowment for International Peace and the Stimson Centre, Pakistan has sufficient fissile material for 350 warheads.  Syria has been part of the Non-Proliferation Treaty since 1969 and has a limited civilian nuclear program. Before the advent of the Syrian civil war, it was known that only a small Chinese research reactor, the SRR-1, was operated. Although it supports a free zone for weapons of mass destruction in the Middle East, the country has been accused of pursuing a military nuclear program with a reported nuclear power plant in an area of Lar ez-Zor. The reactor components were probably designed and manufactured in North Korea, the reactor being remarkably similar to the shape and size of North Korea`s Yongbyon Nuclear Scientific Research Center. This information has alarmed the Israeli army and secret services so much that the idea of a targeted air attack has been imagined.
It led to Operation Orchard, which took place on 6 September 2007 and brought together up to eight Israeli aircraft. The Israeli government reportedly rejected the idea of the operation by the US Bush administration, although the latter refused to participate. The nuclear reactor was destroyed in the attack, which also killed a dozen North Korean workers. The attack did not provoke international outcry or serious Syrian retaliation, as both sides tried to keep it a secret: despite a half-century state of war declared by neighbouring states, Israel did not want publicity about its break-up of the ceasefire, while Syria was not ready to recognize its secret nuclear program.
