It's more the opposite of what the propaganda is telling you. Netanyahu is more the creation of Hamas instead of the other way around. Gaza was under Israeli occupation around 20 years ago. Israel unilaterally withdrew from Gaza and removed all of their settlements there. You know, the thing we always tell them they should do? They did that.
A lot of hope around there being a Palestinian state at that time. But then a plurality of Palestinians voted for Hamas. I suppose they saw Israel's gesture of peace as a sign of weakness. That they should fight Israel even harder to get more. Doesn't matter much now why Palestinians voted for Hamasnow, because when they got power there weren't any elections after that. So even if Palestinians don't want Hamas in power anymore, they can't vote them out. Classic story of fascists taking power with a plurality of the votes and then ending democracy. There was a free Palestinian state in Gaza... for about a year. Then it became a failed state because people got duped by fascists.
So that was the end of Ariel Sharon's gesture of peace with a Palestinian state. Not long after that, Israelis turned to Netanyahu to protect them from the psychopaths that now controlled Gaza.
Many in the "pro-Palestinian" movement are too young to have been around when these things happened. Even if they were, the facts are too inconvenient to admit to. So you aren't going to ever hear about the ugly truth about Hamas from your peer group. There actually was a free Palestinian state in Gaza and it was killed by Hamas. But that was only after Yasser Arafat killed the previous attempt in the 1990s, but that's another story. For there to be a Palestinian state, Palestinians have to choose having a state over hatred of Israel. With the rhetoric I see being promoted, I don't see that happening any time soon.
