I see what you mean, but on the other hand, the Palestinians are occupied by Israel, barred from trading by Israel and Egypt, beholden to Israel for water and power - so one could say that if Israel lifted the sanctions Palestinians might not need to "keep going". Again I think the parallell to the Warsaw getthoes apply - the Jews and others interned could just have accepted their plight. But it would've been the wrong path.

I'm by no means saying Palestinians have a carte blanche - I'm just saying that calling the attacks "unprovoked" is a bit of a stretch?
