The Iranian regime is taking advantage of President Donald Trump’s clear desire to end the war.

The two sides continue to wrangle over the contents of a one-page memorandum that would conclude hostilities and the framework for negotiations that would follow.

Trump yesterday dismissed out of hand the regime’s latest proposal, which was delivered to Pakistani mediators at least three days later than expected.

Details of the Trump administration’s demand for sweeping rollbacks of the Iranian nuclear program are immensely complicated, and the regime is deeply reluctant to concede anything on that front.

Trump constantly has threatened to resume the heavy bombing of regime targets that ended when a ceasefire was implemented on 8 April.

But it is not clear what more bombing would achieve and Trump frequently has said the war is all but over.

The regime’s Islamic Revolutionary Guard Corps (IRGC) has gained leverage since the bombing began on 28 February by choking the Strait of Hormuz, the narrows at the mouth of the Gulf through which 20 percent of global oil supplies and other important commodities normally pass.  Fuel prices have surged around the world, including in the United States.

In response, the US Navy since 13 April effectively has blockaded Iran by tracking ships that make port calls and intercepting them outside the Gulf.  Iran, which already was under acute economic pressure, has been unable to export oil as a result.

The ceasefire was rattled last week when the IRGC and US military exchanged fire in the Strait and the IRGC attacked several commercial vessels and the United Arab Emirates, a US ally.

Rather than respond forcefully, Trump backed off his newly announced initiative to have the US military guide and if necessary protect stranded commercial ships exiting the Gulf through the Strait.

Kuwait, Qatar and Bahrain, which host major US military contingents, all responded to relatively minor Iranian drone incursions over the weekend.  Washington so far has played down that blatant needling by the IRGC.

The Shia fundamentalist Iranian regime is apocalyptic in outlook and is engaged in what it considers an existential war against the US and Israel, its chief ideological foes.  It is well practiced in deception and delay in dialogue with the West.

The current standoff could continue for weeks, with the possibility that developments will spin out of control, leading to the re-eruption of major fire across the Gulf.

The Gulf Arab countries routinely are arresting people, including Westerners, who share cell phone videos of or social media posts about local military assets and Iranian missile and drone impacts. 

Israel and the Lebanese government on 23 April extended their ceasefire agreement for three weeks, keeping in place the lull in fighting between Israeli forces and the Lebanese Shia militia Hizbollah, an Iranian proxy.

That fighting has rekindled in the past two weeks, with Israel last Wednesday staging an airstrike in Beirut for the first time since the ceasefire went into effect on 16 April.  

Full-scale hostilities between Israel and Hizbollah almost certainly would re-erupt if the US-Iran ceasefire collapses.
