“Net serious destabilization of Middle East.”
Not necessarily. Iran’s pipeline for shipping weapons to Hezbollah is broken. It may not come back. Syria’s perpetual interference in Lebanon may be greatly reduced. Removing Russia from the area gives Israel more freedom to prevent weapons from getting into Lebanon and Southern Syria.
Plus, is it possible that the Sunni conquerors will join or tacitly work with the Abraham Accord countries (all Sunni).
So it’s possible that the constant warfare of Hezbollah against Israel will go way down. That’s a massive contributor to Stabilization in the middle east.
No. The Islamists hate Israel. The difference is that this time they're Sunni. And backed by Turkey instead of Iran.
I expect the extermination (Ethnic Cleansing) of Christians in Syria (more severe than Lebanon), and increased violence toward Kurds, however I have a very slight chance of being wrong.
