Military tensions between the United States and Iran reached a critical point on February 28, 2026, as U.S. President Donald Trump confirmed "major combat operations" following an Israeli preemptive strike. The escalation comes after three rounds of indirect nuclear negotiations mediated by Oman, which concluded without a deal earlier this week.
Timeline of Diplomatic Efforts
February 6, Muscat: The first round of talks saw cautious optimism. U.S. officials called discussions "very good," while Iran emphasized a "positive atmosphere" but insisted talks focus solely on nuclear issues.
February 17, Geneva: A second round addressed technical nuclear details, with both sides acknowledging "constructive" progress. Draft frameworks were prepared, though Iran reiterated demands for sanctions relief.
February 26, Geneva: The final round ended with no agreement despite "significant progress" reported by Iranian Foreign Minister Seyed Abbas Araghchi. Plans for technical talks in Vienna on March 2 were canceled after this weekend's military actions.
Iran has closed its airspace amid ongoing strikes, raising concerns about regional stability. Analysts warn the conflict could disrupt global energy markets and complicate security dynamics in the Middle East.
