The clock, it seems, is ticking.
President Trump has given the Iranians 48 hours to make a deal to reopen the Strait of Hormuz, or else, in his words.
All hell will drain down on them.
Unmentioned in that social media post was another race against time inside Iran.
The search for a missing US airman who was on board an F-15 fighter jet shot down apparently
over the southwest of the country on Friday.
According to US officials, the pilot of that plane was rescued,
as was the pilot of another jet that crashed near the Strait of Hormuz.
A Black Hawk helicopter involved in the rescue mission was reportedly hit by fire but managed to escape.
All of this as the attacks on Iran's infrastructure have continued.
Israel said today it has struck petrochemical factories.
Several deaths have been reported in Iran,
while Iranian media have said one person died in an airstrike on the nuclear power plant at Bushir.
For its part, Iran has continued to fire both physical and rhetorical weapons,
targeting Israel, Iraq and the Gulf countries with missiles and drones.
While threatening in familiar-sounding terms to create a regional hellscape for the US
and Israel if they escalate their actions.
Later in the programme we 'll consider what all of this might portend,
