US and Iran Reach Preliminary Nuclear Agreement Amid Military Buildup

The United States and Iran reached a general agreement on guiding principles for a potential nuclear deal during a second round of indirect negotiations in Geneva on February 17, 2026. Mediated by Oman, the talks involved U.S. envoys Steve Witkoff and Jared Kushner and Iranian Foreign Minister Abbas Araghchi. While both sides reported progress, significant gaps remain; the U.S. demands zero uranium enrichment and limits on ballistic missiles, while Iran seeks the verifiable lifting of sanctions and refuses to negotiate its missile program.

The diplomacy occurred against a backdrop of severe military escalation. President Donald Trump deployed a massive naval armada to the region, including the USS Gerald R. Ford and USS Abraham Lincoln, and issued a 14-day ultimatum to Iran. In response, Iran's Islamic Revolutionary Guard Corps conducted live-fire missile drills and temporarily closed parts of the Strait of Hormuz. Supreme Leader Ayatollah Ali Khamenei warned that the U.S. military could be struck so hard it cannot recover, specifically threatening to sink American warships.

To incentivize a deal, Iran proposed providing the U.S. with economic benefits in the energy, mining, and aircraft sectors. Meanwhile, the U.S. coordinated with Israel to restrict Iranian oil exports to China. Despite the agreed-upon principles, U.S. officials, including Vice President JD Vance, cautioned that Tehran has not yet acknowledged the administration's red lines, leaving the possibility of military intervention open.
