This war exposing the limits of US military power. Make no mistake it is the greatest military power, and can strike anyone, anywhere at will. But the economical cost of the war is dawning on people. We are going to see the cost escalate to $1T if not more. Even more important is understanding winning a war is not raining the missiles. Your enemy may survivor after all and suddenly in spite of their total destruction, you may be the loser. Instead of you rewriting the terms, they may end up rewriting the terms.
Some/ many of the hawks who wanted to bomb Iran and kill their leadership may not accept this publicly, but I am hoping many reasonable people could move there. The call for war on anyone and everyone we don’t like will go down a lot.
