This is a very true argument—that if the U.S. wants Iran to change, the U.S. itself must be willing to commit (through a treaty) to that same agreement.  Note also that this is a full board opinion piece.  “Biden Should Aim for a Treaty, Not a Deal, with Iran,” Editorial Board, Bloomberg, June 4, 2021.

Politico is getting on this boat after it left the dock, a few days late on this story.  But more interesting is to observe that the media in general does not report on or investigate the “why does this matter” aspect of the story.  After years of Iranian naval activity (usually closer to home), what good purpose for Iran or good purpose for other countries does the IRGC provide?  Anti-smuggling?  Anti-piracy?  Patrolling straits?  Providing humanitarian assistance?  Defense?  No, Iran’s Navy and “coast guard” is not built for nor does it provide these services that a normal navy does.  So it is up to Politico to look back so that it can know what questions to ask about the present, and the future.  “Iranian warships appear to begin first Atlantic crossing as U.S. warns against weapons transfers,” Lara Seligman and Nahal Toosi, Politico, June 4, 2021.

“Iran wants action, not promises, to revive nuclear deal, Khamenei says,” Reuters, June 4, 2021.

I don’t think so.  Experience in these election decisions by the Supreme Leader shows they are usually final.  “Decision to remove candidates from Iran election to be reviewed,” Reuters, June 4, 2021.
