The blog post said that the Iran war costs the US at least 1 billion USD per day. The US is incredibly rich and can afford the cost. What I don't see being discussed: What if the US (and Israel) does not put troops on the ground in Iran, but continues relentless, daily aerial bombing... forever (1/2/3 years)? I am not saying that you can control a country from air superiority only (this has been widely discussed by military strategists -- it cannot), but you can endlessly bomb their military assets. What would happen? Honestly, I don't know. I don't think it has been done in the last 50 years of war. (Please provide counter examples if you know any.)
