It’s a total victory for Israel, stabbed in the back by Sunnis at the worst possible time, at the height of conflict between Hezbollah and Israel. To continue to support Palestine at this point would be suicide for the now Lebanon, Yemen, Iraq, and Iran axis.
If the Sunnis wanted to support their fellow Sunnis in Palestine, they had the opportunity, both from Idlib with long-range high-tech drones, from Jordan and Egypt with militias, right next door to West Bank and Gaza, and from Turkey with economic sanctions, especially on oil.
There is no alternative scenario, Israel takes Gaza.
