Nah, they're both bad guys. When Palestine was still under British mandate, many of the people who'd become leaders of the state of Israel were just terrorists the same way we'd view Hamas now. And Hamas are scum, the videos they've released themselves over the weekend prove it.
If you want to blame anyone as the creator of this situation... look at the UK and Europe, who decided that the best way to provide justice for the crimes against Jews Europe's inflicted (for centuries, not just the holocaust) would be to make the Middle East pay for it.
I agree that Israel (and the average Israeli citizen) has got a lot more power to determine how the future looks than Hamas, the Palestinian Authority, or any average Palestinian does. They live in a democracy. They have western support. They have an actual military. Breaking the cycle that feeds into extremism will only happen when they break the cycle.
The Nakba was a horrific crime against humanity. But surprise, surprise... so were the Jewish pogroms of the Arab world that went from the 1800s-1960s. This didn't just start in 1947. There's a long history of atrocity here. It's nowhere near as black and white as any slave rebellion.
