Regardless of who is president next the war with Iran will continue. I would absolutely love to be wrong. This has been in the planning for a very long time and he just happened to be the first one to assist Israel. We could speculate why, probably some level of narcissism and wanting to be in history books but the reason won't matter. It's too late, the deep state will not let anyone back out after a taste of funding.
If you would like some deeper discussion on the topic there is a halfway decent talk from Professor Jiang on DOAC. [1] He had many of the same predictions I had mentioned here on HN some time back which nobody here agreed with and they have all come true. We are just getting started in this quagmire.
Don't let Fox news mislead people into thinking that air strikes will do anything to end this.
