It won’t be hard to see what Iran is doing, but it will be easy for the Western left to pretend it isn’t happening. Throughout the process, the mullahs will be watching for the most opportune time to go nuclear. They do ultimately want to do that, but they want to box Israel in first, lull potential antagonists like Saudi Arabia into complacency (or at least into distraction and fatalism), and time it so that there will be no effective ability to respond in Washington or Brussels.
As long as Iran hasn’t actually pulled the trigger yet, the West will avoid taking action, its excuse ready to hand. The beauty of Joe Biden’s promise is that, for the next couple of years, he probably can keep it – if radical Iran continues to play the long game she’s been playing. As “good news,” that will be on a par with driving drunk every day and congratulating yourself if you don’t have an accident.
