Iran is apparently calling the shots here. It hasn't faced the consequences of attacking the US and is unlikely to. Hitting its proxies is not the answer. That is a way too predictable and tired approach by US Pres. Joe Biden, proving again that his bite is as feeble as his bark.
Faced with the prospect of an all-out war in the Middle East, Biden is taking a practical approach to US retaliation. A direct strike on Iran will guarantee an escalation in the conflict, which, for all practical purposes, would be unsustainable. Pin-pointed surgical strikes that do maximum damage to the rogue nation's strategic tentacles are what the US must aim for.
Though the Western media may portray Iran as a rogue state acting belligerently, in reality, US foreign policy is the primary driver of violence and instability in the Middle East. By occupying countries in the region like Iraq and Syria while ruthlessly supporting Israel's brutal campaign against Palestinians in Gaza, the US has directly thrown fuel on the fire of regional tensions.
