History is unwritten. Mass global action against Israeli interests could weaken the state significantly and its relation with the US, and could allow for ruptures within Israeli society and the defeat of the Zionist project. All it takes is collective organization. Neither of us has a crystal ball. To paraphrase Marx: "you can advance just one day in 20 years, and then 20 years in one day".
Your point regarding the Arab states: so apparently you are in favour of Arab states opening their borders, but not the much richer Israel or the much richer and more spacious USA and the Palestinians being given a choice? How funny.
Your point about the end of Israel: if a state can only exist by keeping millions of people in exile or in ghettoes, it tells you soemthing about the legitimacy of the state.
Regarding your other point, I am politically active, and have the right to debate on a forum in my spare time. If you don't want to read my grievances, don't click the thread. Otherwise, debate, and don't just shout "stop whining" like a petty authoritarian.
