One constant in US President Donald Trump's malleable foreign policy has been his fierce criticism of Iran and what he described as a weak and dangerous nuclear deal the US and other countries negotiated with Iran.
Threats and sanctions, and lots of them, have been his go-to response, lately leavened with vague offers of future negotiations.
Trump's reaction to attacks on two commercial tankers near the Strait of Hormuz may reveal the limits of his strategy of squeezing Iran's oil-dependent economy. "Iran did do it," Trump told Fox News, hours after the US miliary released footage it says shows a small Iranian ship sidling up to a damaged tanker and crew removing an unexploded mine. "You know they did it because you saw the boat. I guess one of the mines didn't explode and it's probably got essentially Iran written all over it," Trump said.
The tanker incident pushed tensions to a new height, with fears of a deliberate or accidental armed clash between US and Iranian forces.
"I do not see Trump as worthy of any message exchange, and I do not have any reply for him, now or in future," Supreme Leader Ayatollah Ali Khamenei's website quoted him as saying in response to an offer of dialogue.
