What happens if Donald Trump follows through on his most extreme threat yet? At a chaotic White House briefing, Trump claimed he could wipe out Iran’s infrastructure….. in a single night.

He also demanded free passage through the Strait of Hormuz, even floating the idea of charging global shipping to use it.
