The 2015 JCPOA required Iran to surrender 98% of uranium stockpile, dismantle centrifuges, and accept IAEA inspections in exchange for sanctions relief. Trump's withdrawal in 2019 restored sanctions and prompted Iran to significantly expand nuclear activities, raising proliferation risks that the agreement had contained.

U.S. policy instability undermines multilateral diplomacy; Iran strengthens nuclear capabilities in response to sanctions; China and Russia gain influence as alternative partners to Iran; Israel maintains military leverage; EU credibility in nuclear non-proliferation weakened by U.S. withdrawal.
Similar to the 1973 oil embargo aftermath, regional powers are diversifying partnerships and military capabilities in response to U.S. policy unpredictability, increasing zero-sum competition.
