It is not a matter of debate whether Israel should or should not exist; they have existed for 60+ years, and with their military might and direct anchor support from the United States, their existence is not going to be questioned.
The issue is the government's treatment of the native Palestinian population & the thinly veiled desires of right-wing Zionists for expansion into other countries in a "Ersatz Israel" (Greater Israel) encompassing their surrounding Arab neighboring countries.
