There’s really no point in history we can use to say “there, this makes X side justified and Y side the bad guys!”
Pogroms in Russia left Jewish scholars to conclude that they would only see respect and freedom if they had their own state. That morphed over time into a nationalist movement with violent insurgents.
Palestinians were just living under British colonial rule. They wanted freedom and independence too, and cooperated against violent insurgents. They wanted their land in full and to not have to give it away to and accommodate other people. And over time that’s morphed into groups like Hamas that want every Israeli dead and Israel destroyed.
Their causes have all done damnable things at some point. Their causes started from wanting fundamental freedom and independence and safety.
