Saudi Arabia and Kuwait have lifted restrictions on the U.S. military’s use of their bases and airspace imposed after the start of the American operation to reopen the Strait of Hormuz, according to U.S. and Saudi officials, removing a hurdle that had tripped up President Trump’s effort to move ships through the vital waterway.

The Trump administration is now looking to restart the operation to guide commercial ships with naval and air support that it had paused after 36 hours this week, U.S. officials said. It isn’t clear when that could happen though Pentagon officials gave a timeline of as early as this week.

The U.S. operation to force open the strait relied on an enormous fleet of aircraft to protect commercial ships from Iranian missiles and drones, making Saudi and Kuwaiti bases and airspace critical to its execution.

But the mission set off the biggest dispute in Saudi-American military relations in recent years, triggering a spate of high-level phone calls between Trump and the kingdom’s crown prince and raising the risk of a breakdown of a security deal between Washington and Riyadh.
