Reading messages from President Donald J. Trump is an exercise in taunting masochism. It is one inflicted on commentators and the press corps the world over, and they are not better for it. The latest – and here, the latest will become distant and dated shortly – is that the Strait of Hormuz, predictably controlled by Iran with devastating global effect, was to be reopened for commercial traffic under certain conditions. Trump thought this undertaking absolute and indefinite, a rich suggestion coming from a man with such a fair-weather mind. “Iran has agreed to never close the Strait of Hormuz again. It will no longer be used as a weapon against the World!”

This proved typically premature: within a matter of hours, Iran’s decision was, if not reversed, then heavily qualified. (The Strait technically always remained open to vessels favoured by the Iranian authorities.) On April 17, Iran’s Foreign Ministry spokesperson Eshmaeil Baghaei affirmed two key principles in Tehran’s policies: Iran retained the right to control traffic moving through the Strait, and that it would not surrender enriched uranium, an issue “sacred to us as Iranian soil” and non-negotiable. The latter was certainly aimed at Trump’s dotty claim that Washington and Tehran would jointly deploy “lots of excavators” to remove fissile material (“nuclear dust”) and shift it to the U.S. On CBS News, the president claimed that “Our people, together with the Iranians, are going to work together to get it.” This all suggested much confusion on the part of the Americans.

Iran’s moves on the Strait were always going to be governed by other impediments. There was the demand, for instance, that Washington release $20 billion in frozen Iranian assets. This was rejected. Trump has also insisted on a continued blockade of Iranian ports, which currently employs over 12 warships and something in the order of 100 fighter and surveillance aircraft. As he told Fox News, “we’re not going to let Iran make money on selling oil to people that they like and not people that they don’t like.” Maritime intelligence on this, however, suggests that the blockade has not been quite as effective as heralded by U.S. officials. Martin Kelly, Head of Advisory at EOS Risk Group, can point to the successful passage of sanctioned tankers and vessels of the shadow fleet, such as LPG carriers Crave, Raine, and NV Aquamarine.

On April 18, the Islamic Revolutionary Guard Corps (IRGC) Navy issued a statement that “no vessel is to move from its anchorage in the Persian Gulf or the Sea of Oman.” A number of vessels had successfully managed to pass through under supervision since Friday night, but the Strait would be closed till the U.S. ceased blocking Iran’s ports. “Approaching the Strait of Hormuz will be considered cooperation with the enemy, and the offending vessel will be targeted.”

The IRGC have been true to their word. According to UK Maritime Trade Operations, the Master of a tanker reported “being approached by 2 IRGC gun boats” without a VHF challenge, “then fired upon the tanker.” No injuries were sustained. Another report documented “a Container Ship being hit by an unknown projectile which caused damage to some of the containers.” There were no fires or environmental impacts reported. A third incident involved the sighting by the Master of a cruise ship of “a splash in close proximity to the vessel,” regarded as suspicious.

The ongoing U.S. blockade, argues Iran’s Supreme National Security Council (SNSC), was also a violation of the ceasefire agreement between Tehran and Washington. As Tehran revealed in a statement, passage through the Strait would only take place through a “designated route” and only with Iranian authorisation. The opening or closing of the Strait, along with pertinent regulations governing it would be “determined by the field, not by social media.” The Council has also revealed that it is reviewing new proposals from the U.S. that may form the basis of future talks.

Trump has also huffed that the latest developments in the Strait were “not tied, in any way, to Lebanon,” a barely plausible contention. Iran has insisted that any lasting ceasefire manoeuvres would have to include a cessation of Israeli strikes on Lebanon and Hezbollah positions, even if negotiations between the U.S. and Lebanon did not involve any mention of the Shia militia. The U.S. president duly went on Truth Social to bluster that Israel “will not be bombing Lebanon any longer.” They were “PROHIBITED from doing so by the USA. Enough is enough.”

The somewhat devalued currency of a ceasefire did not, as it was subsequently confirmed, prohibit Israel from resorting to its right to self-defence, a right so latitudinous as to be boundless. Israeli Prime Minister Benjamin Netanyahu promised that things were far from concluded. “I will say honestly, we have not yet finished the job.” Remaining rocket and drone threats needed neutralisation. Hezbollah would have to be dismantled through a “sustained effort, patience, and careful navigation in the diplomatic arena.”

There was also much room for lashing reluctant allies. “Now that the Hormuz Strait situation is over,” declared Trump, “I received a call from NATO asking if we would need some help.” With the usual flourish of petulance, he dismissed the call: Stay away unless you want to load up with oil. “They are useless when needed, a Paper Tiger!” Increasingly, the U.S. imperium is resembling that tiger, incapable of stalking and capturing its far more resourceful prey.
