I believe the state of Israel has a right to continue existence because the citizens, both Arab and Jewish want it to be that way. That's self-determination.The original and the new definitions, are both, illegitimate and colonial in nature. It is religious mumbo jumbo.
But you support Zionism, which is religious mumbo jumbo.
And I also support a Palestinian state beside Israel because the Palestinian people detest a One State peace. 75% of them reject both a One and two State peace so getting there will be problematic but that's what I support. I would also be okay if Israelis and Palestinians themselves decided to enact a One State peace but less than 5% of the population support that.
