the reality is that the framing here is inaccurate. the americans are not launching strikes against some kind of rebel groups, they're retaliating to protect their shipping interests and are probably taking out literal iranian weapons sites. it is inconceivable that the united states could look the other way and ignore it's commercial interests getting bombed.
the reality is that the people that live in this region have a very long history of attacking trade interests, going back into antiquity. these are literal barbarians, and they've been bombing caravans for centuries.
