Trump weighs putting boots on the ground in Iran

What happened

President Trump lashed out at U.S. allies this week after they rebuffed his demand to help break Iran’s blockade of a crucial oil shipping route, as the energy shock unleashed by the U.S.-Israel war with the Islamic Republic reverberated around the globe. Traffic through the Strait of Hormuz—the Persian Gulf channel that carries 20% of the world’s oil—has slowed to a trickle since the war started on Feb. 28, causing the cost of crude to spike more than 50% to above $110 a barrel.
