The IDF cannot eliminate every Hamasnik in Gaza. It's physically impossible. Hamas is recruiting new foot-soldiers every day. Even if it were technically possible, it could not be done without killing and/or maiming hundreds of thousands of non-combatants. That would be a war crime which the world will not accept (and Israelis shouldn't accept it, either).
