Iran just raised the stakes in the Gulf. Today, military officials announced that U.S. military supplies are officially banned from the Strait of Hormuz.

This comes as President Trump warns the current ceasefire is on "life support." With the "gatekeeper" of Hormuz tightening the lock, the risk of a major naval confrontation is higher than ever.
