Signed by China, France, Germany, Russia, the U.K., the United States and Iran, the <a href=\"https:\/\/2009-2017.state.gov\/e\/eb\/tfs\/spi\/iran\/jcpoa\/\" target=\"_blank\" rel=\"\" title=\"https:\/\/2009-2017.state.gov\/e\/eb\/tfs\/spi\/iran\/jcpoa\/\">Joint Comprehensive Plan of Action<\/a> (JCPOA) halted Iran\u2019s development of nuclear technology and stockpiling of nuclear material in exchange for lifting multiple international economic sanctions placed on Iran. Ballistic missile technology and Iran\u2019s proxy support for regional militias were not included in the original agreement due to Iran\u2019s unwillingness to include those measures.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The parties to the Iran deal ultimately decided that a nuclear deal was better than the alternative of no deal at all.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There was a window for such a deal to be resumed in between the two Trump administrations. And the Biden administration publicly <a href=\"https:\/\/www.cfr.org\/articles\/bidens-first-foreign-policy-move-reentering-international-agreements-2\" target=\"_blank\" rel=\"\" title=\"https:\/\/www.cfr.org\/articles\/bidens-first-foreign-policy-move-reentering-international-agreements-2\">pledged to strengthen and renew<\/a> the Obama-era nuclear deal in 2021.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But by then, Iran had <a href=\"https:\/\/www.armscontrol.org\/factsheets\/status-irans-nuclear-program-1\" target=\"_blank\" rel=\"\" title=\"https:\/\/www.armscontrol.org\/factsheets\/status-irans-nuclear-program-1\">significantly increased its nuclear technical capability<\/a> during the four years that has passed since the JCPOA collapsed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That increased the difficulty: Just to return to the previous deal would have required Iran to give up the new technical capability it had achieved for no new benefits.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The window closed in 2022 after <a href=\"https:\/\/www.aljazeera.com\/news\/2022\/6\/8\/iran-dismantles-nuclear-monitoring-cameras-after-iaea-censure\" target=\"_blank\" rel=\"\" title=\"https:\/\/www.aljazeera.com\/news\/2022\/6\/8\/iran-dismantles-nuclear-monitoring-cameras-after-iaea-censure\">Iran removed all<\/a> of the International Atomic Energy Agency\u2019s surveillance and monitoring under the deal and started enriching uranium to near weapons levels and stockpiling sufficient amounts for several nuclear weapons.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The IAEA, the U.N\u2019s nuclear watchdog, currently maintains only normal safeguards Iran had agreed to before the JCPOA.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Even with the 2025 U.S. strikes, Iran currently has the ability to produce enough fissile material for a nuclear bomb within weeks to several months.

(Jesse Monford\/U.S. Navy via Getty Images)\n<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">US and Iran talks today<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Although most analysts doubt that Iran has developed the weaponization knowledge necessary to build a nuclear bomb \u2014 estimates vary from several months to about two years due to the lack of access to and evidence on Iran\u2019s weaponization research \u2014 Iran\u2019s technical advances reduce the value for the U.S. government of returning to the 2015 deal. Iran\u2019s knowledge cannot be put back into Pandora\u2019s box.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But talks do not necessarily need an end point \u2014 in the shape of a deal \u2014 for them to have purpose.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With the increased military brinkmanship, talks could help the U.S. and Iran step back from the edge, build trust and perhaps develop better political relations. Both sides would benefit from this stabilization: Iran economically, from being reintegrated into the international system, and the U.S. from a verifiable lengthening of the time it would take Iran to break out.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">None of this is guaranteed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When I worked in multilateral nuclear diplomacy for the U.S. State Department, we saw talks fail in 2009 regarding North Korea\u2019s nuclear weapons program, after six years of on-and-off progress. The consequence of that failure is a more unstable East Asia and <a href=\"https:\/\/www.csis.org\/analysis\/will-south-koreas-nuclear-ambitions-subside-next-five-years\" target=\"_blank\" rel=\"\" title=\"https:\/\/www.csis.org\/analysis\/will-south-koreas-nuclear-ambitions-subside-next-five-years\">renewed interest<\/a> by South Korea in developing nuclear weapons.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unfortunately, the same dynamic appears here. The shape of a potential new deal is unclear. As time passes with no deal, both sides harden their negotiating starting points, making a deal less likely.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Military escalations may lead to a new willingness to compromise on the part of Iran or precipitate its decision to build nuclear weapons.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But even should the talks prove a failure, the effort to dampen the confrontational responses and heightening tensions would still be valuable in reducing the possibility of regional conflict.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><i>Nina Srinivasan
