United States in March 2026: the most important developments in security
In March 2026, security news in the United States centred on the war with Iran. On March 1 Iran said its supreme leader, Ali Khamenei, had been killed in US and Israeli strikes, and it launched missile and drone attacks on US bases and on Israel. President Trump said on March 2 that the conflict could last several weeks, and on March 9 that it was "very complete." By March 29 the Pentagon was reportedly drafting plans for limited ground operations, with no decision made, and about 2,000 troops of the 82nd Airborne Division were ordered to the Middle East.
The Strait of Hormuz and Kharg Island, Iran's key oil export terminal, were the main questions. On March 10 Trump warned Iran against blocking the strait and said US forces had destroyed 10 mine-laying vessels; on March 12 US military officials said they could not yet escort ships after 16 were hit. He said on March 13 that the US had bombed Kharg Island, while Iranian media reported no significant damage to oil facilities. On March 23 he delayed strikes on Iranian energy sites, citing good conversations that Iran denied, and extended the pause into April. On March 30 he threatened to destroy or seize Kharg Island if no deal was reached.
US forces and facilities were attacked repeatedly. Six service members died on March 12 when a KC-135 tanker crashed in western Iraq. The US embassies in Riyadh and Baghdad were hit, and on March 28 an Iranian strike on a Saudi base wounded 10 to 12 US troops. A US investigation found American forces had likely struck a school in Minab, Iran, citing outdated intelligence.
At home, the FBI opened terrorism investigations into a bar shooting in Austin that left three dead, a bomb thrown near the New York mayor's residence, and a synagogue attack in Michigan that it said was inspired by Hezbollah. ICE agents were deployed to major airports on March 23 during a partial government shutdown, and an Air Canada Express plane hit a fire truck at LaGuardia Airport that day, killing both pilots.
