Defense Department adviser on nuclear deterrence policy, told VOA that Iran could use that time to build a 'gun-type' nuclear bomb. Georgetown University international relations professor Matthew Kroenig, who previously served as a U.S. 'Iran could rush to its first nuclear explosive, in our estimate, in about three months,' Albright said. physicist David Albright, president of the Institute for Science and International Security, told VOA Persian in a recent interview that Iran also could develop a cruder nuclear weapon in a much shorter time once it achieves a breakout capacity.

Israeli officials have estimated it would take Iran two years after attaining a breakout capacity to develop, if it wanted, a nuclear-armed missile that could reach Israel. Israel long has viewed a nuclear-armed Iran as an existential threat because of repeated calls by the Islamic Republic for the destruction of the Jewish state. The International Atomic Energy Agency says 25 kilograms of the uranium-235 isotope, which is accumulated when about 28 kilograms of uranium is enriched to 90% purity, is the breakout quantity at which the 'possibility of manufacturing a nuclear explosive device cannot be excluded.' The agreement was intended to prevent Iran from producing enough highly enriched uranium to make one nuclear bomb. The U.S and Iran decided to start indirect talks in Vienna last year, through the mediation of world powers, after President Joe Biden succeeded Trump and pledged to rejoin the JCPOA if Iran would return to limiting its nuclear activities under the deal.įILE - Enrique Mora, of the European External Action Service, and Ali Bagheri Kani, Iran's chief nuclear negotiator, wait for the start of talks on the Iran nuclear deal in Vienna, Austria, Dec. Iran retaliated a year later by starting a process of increasingly exceeding JCPOA limits on its nuclear work. left the 2015 deal, known as the Joint Comprehensive Plan of Action, or JCPOA, in 2018 when then-President Donald Trump said it was not tough enough on Tehran and unilaterally reimposed U.S. Iran says its nuclear activities are for civilian use and denies seeking nuclear weapons. 'I think that will be decided in the next few weeks, because again, given what Iran is doing, we can't allow this to go on,' Blinken said. and Iran have been negotiating indirectly since last April to see if they can secure a mutual return to compliance with a 2015 deal in which Tehran promised to curb nuclear activities that could be weaponized in return for sanctions relief from the U.S. Secretary of State Antony Blinken speaks during a briefing at the State Department in Washington, Jan.
