Although that would be the best way out, it is also unlikely as so many in the US elite are Israel-firsters. They would rather let the US go down than abandon Israel. Their allegiances are to those dark forces who actively pushed for this war and who deliberately forced Iran to respond when they hit the children's school on the very first day. The push for continued war by sabotaging peace efforts shows that they are likely not done yet.Third way: bow out and let Israel deal with their mess alone.
