As warlike provocations go, it was more like something stoned teenagers would come up with. Not that I think the speed boats circling around US warships off Iran really were piloted by stoners. It was just a really stoned thing to say: "In a few minutes you will explode."
No one exploded. So the provocateurs just look kind of stupid. Scary, but stupid. Then again, violent, stupid, deranged people are the scariest.
That does not make another war a good idea. There's no quick and simple answer to this. In fact, it could have been ill-advised ball-busting.
What's the diplomatic version of, "What the fuck was that?"
