Paul Krugman: “First, any hopes that this war might be extremely brief are fading. The Trump administration may have imagined that decapitating the Iranian government would bring swift regime change, but the Islamic State isn’t a government of mere thugs — yes, they’re evil thugs, but they’re also serious religious fanatics facing what for them is an existential threat, and their grip on power isn’t that easy to break. Furthermore, it’s painfully obvious that Trump and co. had no plan beyond bombing Iran, killing its current leaders, and hoping that something good would happen.”“Second, war in the middle of the world’s most important oil-producing region — which is also a key source of liquefied natural gas — inevitably has major consequences for energy prices. Once upon a time US and Israeli air superiority might have contained Iran’s ability to harm its neighbors. But in an age in which even third-rate powers have the ability to launch missiles and drones, Iran has a huge stockpile of drones and also has ballistic missiles that are destructive, hard to intercept, and have a 1200 mile range.”
