Vice President JD Vance went on ABC’s Good Morning America on June 15 and delivered a message that was equal parts diplomatic optimism and gentle arm-twisting: the United States expects Israel to eventually back the newly signed US-Iran memorandum of understanding, even if the two allies don’t see eye to eye on every detail right now.

The agreement, digitally signed over the weekend of June 13-14, represents the most significant diplomatic development between Washington and Tehran in years. Its stated goals include halting hostilities, reopening the Strait of Hormuz without tolls, and tackling Iran’s nuclear program. Oil markets didn’t wait for the fine print, with prices dropping on reports that the critical shipping lane could reopen.

What the deal actually covers

Roughly a fifth of the world’s oil supply passes through the Strait of Hormuz on any given day. Reopening the strait without tolls is the headline economic provision. But the geopolitical core of the memorandum is nuclear: preventing Iran from acquiring nuclear weapons remains what Vance called a “fundamental goal” for the United States.

The full text of the agreement hasn’t been released yet. Vance indicated that a complete disclosure is expected imminently, with verification processes and the removal of enriched materials among the most closely watched provisions.
