U.S. Defense Secretary Pete Hegseth and Joint Chiefs Chairman Dan Caine briefed reporters on the latest developments in the ongoing war with Iran. Hegseth stated that while the U.S. has heard Iran talking about placing new mines in the Strait of Hormuz, there is "no clear evidence" that they have actually done so. The officials also discussed continued U.S. strikes against Iran's ballistic missiles and navy, as well as the impact of the conflict on global oil prices.

Why it matters

The Strait of Hormuz is a critical global chokepoint for oil shipments, and any disruption to shipping in the strait could have major economic consequences worldwide. Iran has previously threatened to block the strait, raising concerns about potential escalation in the region.

The details

Hegseth and Caine said the U.S. is "continuing to destroy the Iranian navy" and targeting Iran's mining capability to prevent attacks on commercial vessels. They stated that the U.S. will not allow the strait to "remain contested." The officials also addressed a recent U.S. military refueling tanker crash in Iraq that killed at least four service members, with two others still missing.

  • On March 13, 2026, Hegseth and Caine briefed reporters at the Pentagon.
  • The U.S. and Israel have struck more than 15,000 "enemy targets" since the war began on February 28, 2026.

The takeaway
