Incorporating the land is not the same as incorporating the people who currently dwell on the land, and use it as a staging area to attack you.
In response to attacks, if Israel was just to take a piece of land in retaliation, and if anyone lives there, tell them to move into Arab territory, the situation would solve itself. Either the Arabs would be peaceful, or they would become citizens of Egypt and Jordan.
Forcefully moving population groups out of areas and then taking them over — is one of the definitions of a WAR CRIME ... and Israel doesn’t do war crimes.
In fact, Israel is currently and FALSELY ACCUSED of doing such things now, by the enemy - and then we find the so-called supporters of Israel (usually ignorant) actually encouraging Israel to commit the very war crimes that Israel so vociferously DENIES and the enemy LOUDLY PROCLAIMS!
