I tried adding to the existing post on Gaza,but couldn't,so...
It seems that Israel is just pressurising Palestinians to leave Gaza.
Destruction of houses on a massive scale means some Gazans will want to emigrate.More opportunity for Israeli settlers to take over those devastated villages.This is a political war;Israel is not really threatened by inaccurate Hamas missiles.
Blowing up houses does little to deter Hamas,who wage guerilla attacks.
Better the Israelis come clean and negotiate a new territory for Gazans with their Arab neighbours.Israel is never going to return territory in any meaningful sense to the Palestinians.
