Germans in occupied Poland, Czechoslovakia and France collaborated with the German occupiers. Even though the native Germans lived in these countries for hundreds of years they were expelled after the war. That is but one of the current examples that Israel should follow. Israel must expel these refugees. Gazans for the most part live in refugee camps and are refugees. They are violent savages that cannot co-exist and therefore must be uprooted.
By making Gaza uninhabitable and stopping any humanitarian aid will force the Arab nations to take them in or allow them to either leave voluntarily or die. This is an Arab problem and the Arabs must solve it.
