Stopping killing Palestinians wouldn’t be the end to the conflict, though, so it makes sense that it wouldn’t end hostilities. The end to the conflict would be the end of the ethnostate and institution of a secular society with equal rights to all that recognizes the right of return for Palestinians just as it does for people of Jewish descent. That isn’t a simple solution Netanyahu could do on his own, but it is definitely within the powers of the Israeli state, were there the will or desire.
