Conflict Background

The conflict began on February 28, 2025, when the United States and Israel launched military operations against Iran. The war involved multiple rounds of strikes and counter-strikes, including:

  • US and Israeli strikes on Iranian nuclear, military, and energy infrastructure
  • Iranian ballistic missile and drone attacks on Israel, US bases, and Gulf states
  • Iran's closure of the Strait of Hormuz, disrupting approximately 20% of global oil supply
  • The death of former Supreme Leader Ayatollah Ali Khamenei in US-Israeli strikes
  • Over 5,000 reported fatalities across nearly a dozen countries, including more than 1,600 civilians in Iran

The conflict was marked by multiple ceasefire attempts, mediation efforts by Pakistan, Oman, and Qatar, and shifting US demands ranging from nuclear program restrictions to regime change.

Next Steps

  • Direct face-to-face peace talks are scheduled to finalize details.
  • The 60-day negotiation period will address nuclear issues, sanctions, and a final comprehensive agreement.
  • Iranian state media cautioned that the ceasefire talks do not signify a permanent end to the war until the terms of Iran's peace plan are met.
