you're completely wrong. if the Palestinians would not use violence, they can use diplomacy.
their use of violence has been proven futile every single time it was tried.
with diplomacy, borders could have been negotiated and shifted while enjoying peace and prosperity.
with hatred, only suffering was gained.
we can not prevent the suffering that was already endured, but we can prevent future suffering.
if the palestinians would have accepted the arrival of the jews and israel without resorting to violence at all, then new borders could have been negotiated while enjoying peace and prosperity.
i find the violent-minded pride of the Palestinians and their supporters entirely counter-productive for the Palestinian and Israeli people.
