President Trump is now demanding that Iran reach a deal with Oman on the Strait of Hormuz as soon as today or face devastating attacks from the United States. But this is actually an example of how deep a hole the U.S. is now in, and how rapidly it’s sliding into conceding a system of post-war Iranian tolls on the Strait as a given. What Iran and Oman are negotiating is an interim agreement in which they will jointly manage a system of tolls (calling them “service fees”) over what is an international waterway. But something so fundamental conceded in a provisional or temporary agreement is seldom withdrawn in a final accord. The mix of control and revenue this provides to Iran amounts to a massive strategic gain from the war Trump began back in February.
