US-Iran Nuclear Talks Collapse, Military Buildup

The current standoff follows the 2018 U.S. withdrawal from the Joint Comprehensive Plan of Action (JCPOA), a 2015 deal that curbed Iran's nuclear activities in exchange for sanctions relief. After the U.S. left the agreement and reimposed sanctions, Iran began exceeding the pact's nuclear limits. The recent Omani-mediated talks were steered by U.S. special envoy Steve Witkoff and Iranian Foreign Minister Abbas Araghchi. A core U.S. demand was for Iran to destroy its nuclear facilities at Fordow, Natanz, and Isfahan and ship its enriched uranium out of the country, proposals Tehran flatly rejected. In response to the diplomatic failure, the Pentagon has amassed its largest force in the Middle East since the 2003 Iraq invasion. This includes two aircraft carrier strike groups, led by the USS Gerald R. Ford and USS Abraham Lincoln, totaling at least 16 warships and more than 10,000 service members. The naval buildup is supported by a significant air power deployment, with more than 100 fighter jets, including F-35s, F-22s, and F-15s, moved to regional bases. Satellite imagery shows over 50 aircraft at Muwaffaq Salti Air Base in Jordan alone, part of a massive logistical operation involving over 200 cargo planes. U.S. CENTCOM commander Admiral Brad Cooper has briefed President Trump on military options, which reportedly range from limited surgical strikes on nuclear sites to a broader, weeks-long campaign potentially involving Israel. Senior U.S. officials indicated the military could be ready to launch strikes as soon as Saturday, though no decision has been made. International leaders have responded with alarm, with U.N. Secretary-General Antonio Guterres calling for de-escalation to avoid "catastrophic consequences." European allies, including the U.K., France, and Germany, who tried to preserve the original deal, have urged a return to diplomacy.
