Hope for a negotiated end to the Iran-US war has faded since President Donald Trump on Saturday scrapped a visit by his envoys Steve Witkoff and Jared Kushner to Pakistan, which Iranian Foreign Minister Abbas Araqchi visited twice over the weekend.

Expectations already were low after Vice President JD Vance and Iranian parliament speaker Mohammad Bagher Ghalibaf, senior figures who led initial talks on 11 April that broke down after 21 hours, failed to return to Pakistan as expected last week.

Pakistan today said it continues to work behind-the-scenes on bridging proposals.

The Iranian regime is offering to formalize a ceasefire and fully reopen shipping through the Strait of Hormuz while putting off negotiations over the Iranian nuclear program, according to Iranian sources.

But having declared that the regime will not be allowed to develop nuclear bombs, Trump is unlikely to agree to leave the matter for later.

The upshot is that there is no end in sight to the dueling blockades in which Iran is choking the Strait, through which 20 percent of global oil supplies pass and other important commodities pass in normal times, and the US Navy is enforcing a ban on calls to Iranian ports by tracking ships and intercepting them outside the Gulf.

While neither side seeks a return to full-scale war, events could spin out of control.

Gulf Arab countries face the possibility of Iran’s Islamic Revolutionary Guard Corps (IRGC) resuming missile and drone attacks against them.

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 Thursday 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, however, ticked up over the weekend.   

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