I’m not saying it’s good or bad, I’m saying it’s not the escalation you’re claiming it is. Iran is in an existential war against the world’s strongest superpower. It’s allowed to defend itself, and they have deemed that the best way to do that is to disrupt the global economy to the point that the war isn’t worth it. It’s quite an immediately effective strategy, too, and will hasten the end of the war far faster than bombing schools or whatever it is that the US’s strategy is.
