most palestinians i know want a one state solution because they want equal rights in the country they and their ancestors were born in. i don’t know the consensus among israelis, if there is one, but current political powers in israel don’t want to demilitarize palestine or lift the siege on gaza and also don’t want to afford palestinians the same rights as jewish people.
there is definitely liberal israeli support for the palestinian cause but i’m certain their opinions differs vs an israeli settler, for example.
