The US and Iran have blown past red lines as they lurch back toward all-out war

A week after a tentative U.S.–Iran deal, an Iranian drone hit a cargo ship in the Strait of Hormuz and a rapid cycle of strikes and counterstrikes soon unraveled the agreement.
The Strait of Hormuz — a chokepoint for about a fifth of the world’s oil — has become the flashpoint, so attacks on shipping risk spiking global energy prices.
Diplomacy (with Qatar mediating) and agreed “red lines” have broken down; mixed U.S. signals and widening strikes make a return to broader regional war a growing concern.
