Will it be a democracy? Will it respect minorities Will women and gays have equal rights?
Let them put forth a constitution explaining what type of state they are asking for before they get the support of the world to establish it.
And then if they want a pluralistic liberal democracy, I would be a supporter, especially if Jews could also be citizens. It amazes me how the Palestinians claim Israel is a racist state and then say oh but in our future state not a single Jew or Israeli is allowed to remain.
