Trump has pitted these former allies against each other.They are neutralizing each other, and it cost the U.S.zip. Formerly, Turkey, Iran, Russia and Syria were united against USA. Europeans were not involved and were enjoying U.S. protection of their interests. Now, they are busy having to fight for their interests. This is good for Israel because Iran has to defend Syria against Turkey instead of focusing on Israel.Three enemies of Israel: Iran, Turkey and Syria are facing off against each other. This invasion is going to cost Turkey dearly because it has brought unity between Syria and Kurds, and division between Russia, Turkey and Iran.
