Iran's participation in the 2026 World Cup hangs in the balance as military conflict erupts between the U.S. and Iran just 100 days before the tournament begins. The Islamic Republic, scheduled to play all three group matches in the United States, faces uncertainty after President Trump announced joint operations with Israel against Iran. Longtime leader Ayatollah Ali Khamenei was killed in airstrikes, triggering retaliatory missile and drone attacks.

Iran has qualified for six consecutive World Cups, including the last three tournaments, and is set to compete in Group G against New Zealand, Belgium, and Egypt. However, Iran's soccer federation president Mehdi Taj admitted uncertainty about participation, telling Varzesh3 that "after this attack, we cannot be expected to look forward to the World Cup with hope." Multiple scenarios could prevent Iran's involvement: political boycott, safety concerns, or U.S. government intervention.

If Iran withdraws, FIFA faces complex replacement decisions. The tournament regulations allow for group restructuring or bringing in another team, though finding an obvious replacement proves difficult given the convoluted Asian qualification process. Iran topped their qualification group, with Iraq winning the subsequent playoff and now competing in inter-confederation playoffs. The World Cup begins June 11 in Mexico City, leaving limited time for FIFA to resolve this unprecedented situation.
