Trump and co are still dangerous, even with the sometimes absurd belligerence, because they have the military might of the empire behind them. That military might has cracks showing, especially up against a country as militarily developed as Iran is, but it can still do damage.

Or to put it another way:

Long-term view: The empire is in serious decline, shows no signs of being capable of turning things around, and through its mask off belligerence is currently redefining itself as an overt world terrorist organization (thereby damaging the soft power of the past). A new multi-polar world order is not yet solidified, but Iran's ability to defend itself is solidifying the multi-polar rise against imperial attempts to reassert the uni-polar order.

Short-term view: The empire still has a lot of weapons and can hurt a lot of people with them. Nobody has perfect defenses that can stop every attack and people living in relative peace is better than them dealing with a thrashing beast.

As for Trump himself, he's long been kind of unhinged. Plus narcissists tend to be when backed into a corner. Hypothetically, would it materially change much if Trump himself was no longer making the executive calls but others in his circle were? I would figure, policy-wise, no dramatic changes. But others may be more grounded in terms of the consequences of the flow of oil being disrupted for so long and more willing to make peace deals for that reason. Media management would for sure take a hit, with them struggling to find somebody with the same personality cult draw.

But all of this analysis doesn't mean much with regards to the headline. The fact is, he pissed off enough people for them to want to do this. Whether it would actually lead anywhere, it is a pretty strong statement of hatred of the man coming from the region.
