The Biden administration has put Washington’s Arab allies in the Persian Gulf on notice. Since Jan. 20, the White House has made several decisions that have harmed those allies and strengthened Tehran’s position in the region. A longer-term beneficiary will be China.

The Biden administration came to office with the promise of returning to the Iran nuclear deal, formally known as the Joint Comprehensive Plan of Action, which most Arab states and Israel oppose. They see Tehran gaining substantial economic opportunities from the JCPOA without having to dismantle its nuclear program or curb its regional ambitions.
