We should stop selling bombs to everyone in the region, and pull all of our support. If they want to fight each other, let them. As long as the US blindly supports Israel, they will feel empowered to continue not being peaceful. We won’t though, since Israel is the beachhead of the petrodollar into the region. Just like no US president will stop giving weapons to the Saudis.
Israel is like my chihuahua that is only tough when she is on the leash. Let her off the leash and she is much less vicious to other dogs.
