It is effectively genocide. While it's true they aren't specifically trying to wipe out everyone that's ethnically Palestinian, what they are trying to do is remove everyone living in Palestine who isn't Israeli either by murdering them or causing them to flee into another country. That's close enough to genocide to qualify, particularly when the people murdered by the Israeli army are about half women and children.
Their ultimate goal is the complete elimination of the state of Palestine. Are you seriously going to claim that isn't genocide?
