This does not appear to be real. He did have a similar truth social post:
Tuesday will be Power Plant Day, and Bridge Day, all wrapped up in one, in Iran. There will be nothing like it!!! Open the Fuckin’ Strait, you crazy bastards, or you’ll be living in Hell - JUST WATCH! Praise be to Allah. President DONALD J. TRUMP
The posted image doesnt exist at the date shown in the picture. Its effectively misinformation as its similar to but not actually a thing he posted
Someone posted this archive tool, this link is to the 100 items per page view, you can scroll past the date in the photo and the post doesnt exist: https://www.trumpstruth.org/?per_page=100






Its not really satire I’d its almost exactly what he said but slightly worse, theres not really a joke or commentary and it does succeed at being misleading, I feel like describing it that way is unreasonable. Its just an exaggeration of how bad what he said is.
There are people in this tread litterally claiming its true because there are sources that substantiate him saying something very similar.
