The 20 years of attacks and counter attacks were done by both sides. Looking at the numbers on each side of who were killed is very revealing. But that is ultimately a side issue: there are always "attacks and counter-attacks" when colonists are taking land.

Yes, I do think the Arabs were right to try to protect Palestinians, and will note that your "six armies" is misleading: they were outnumbered by the Zionists, who had better weapons as well.
