Saudi Arabia is pressing the U.S. to drop its blockade of the Strait of Hormuz and return to the negotiating table, fearing President Trump's move to close it off could lead Iran to escalate and disrupt other important shipping routes, Arab officials said. The blockade is aimed at raising the pressure on Iran's already crippled economy. But the officials said Saudi Arabia has warned Iran might retaliate by closing the Bab al-Mandeb"a Red Sea chokepoint crucial for the kingdom's remaining oil exports. The pushback is a sign of the risks and limitations of U.S. efforts to pry open the Strait of Hormuz, which Iran shut early in the war by attacking ships in the waterway, cutting off around 13 million barrels a day in oil exports and sending futures prices above $100 a barrel.
