The U.S. military struck Iranian targets on June 26 in response to Iran's drone attack on a Singapore-flagged cargo ship in the Strait of Hormuz the previous day — marking the first American strikes since the two countries agreed to a ceasefire extension a week earlier. President Trump said the Iranian attack violated the terms of that agreement. This is the most serious test yet of the interim understanding meant to begin de-escalating the months-long US-Israel war on Iran and reopening the critical waterway.
