God knows. I think he's just generally panicking. Earlier tonight (our time, but I think morning in the Middle East), the Iranians blew up an oil tanker anchored in Dubai. Just across the Strait from Iran.
The tanker was full, so that'll be an awful mess. And Dubai and other Gulf countries will be angry. Probably more angry at Trumpty than at the Iranians. I know I would be.
He is perhaps beginning to realize he's made a mess he can't TACO his way out of.
