Egypt and Jordan want no part of Hamas. Bahrain, UAE, Morocco and Sudan have officially recognized Israel. The Saudi were ready to do so up until October 7, although it might happen after things cool off. My point is, most Arab countries are tired of all the conflict going on involving Israel. Iran is the problem. They want to be the supreme ruler of the Middle East. They think destabilizing their smaller and weaker neighbors will help them get there. This is one reason they are supporting Hezbollah and Hamas and other terrorist groups. This is also why they want to become a nuclear power.
Because Israel possess nuclear weapons, having the Israelis on their side would help counter Iran's attempt at dominance.
