Israel’s campaign, militarily and rhetorically, has quickly evolved beyond its initial targets. Over the weekend, it hit Iran’s energy facilities, including a gas depot and an oil refinery, triggering huge fires and spewing smoke across the sprawling capital of about ten million people.

Iran’s “Axis of Resistance,” the network of militias it has fostered in the Middle East to help it fight Israel, has become seriously degraded, experts say.

Israel and Iran exchanged fire for the fourth consecutive day on Monday, stoking fears of an all-out war with the potential to drag in others in the oil-rich region and force the US into a more hands-on stance.
