According to Netanyahu the IDF will leave when Hamas is ERADICATED.
“Hamas moves to reassert power in Gaza City areas from which Israeli Forces withdrew,”.
Now Netanyahu has a problem. All the civilian men, women and children are dead or cleansed from those areas. All of the Hamas controlled schools, hospitals, churches, infrastructure, food, water and sanitation are gone. What guilty civilians are left to shoot or blow up their houses to oust Hamas this time?
Then it's a complete free-fire zone. Anyone left is Hamas and needs to be destroyed, along with any buildings and infrastructure remaining. Sooner the better.
