Trump knocks US-Iran war back to square one

The US-Iran Memorandum of Understanding is effectively dead. A new dispute over how to manage the Strait of Hormuz has pushed both sides back into open conflict. But the fighting may change little. Experts see no clear path to a different outcome. The fundamentals of the standoff remain the same. The Strait of Hormuz is a narrow waterway in the Persian Gulf. About 20% of the world's oil passes through it. Control of this strategic chokepoint is a key source of tension. This round of war, analysts say, risks repeating past cycles. Neither side appears able to force a decisive shift. The result: the conflict has returned to square one.
