Gaza was a failed experiment in “autonomy” and will never be repeated. This as well as Area A and B are self administered territories under the PA and at the pleasure of Israel. They will get autonomy until and unless they start terrorism. Israel is going into Area A and B currently to uproot terror.
Your points 1-4 are completely distorted and are not reality on the ground.
Israel can chock off these delusions very quickly without firing a shot.
