Israel is a European settler colony founded by imperial mandate, so yeah, it needs to be abolished. That doesn't require horror or mass casualties or "obliteration", though. It would be entirely possible to administratively abolish Israel without any need for violence, and all of Israel's citizens could be welcome to become Palestinian in a new multi-ethnic/multi-religious democracy.

So this interpretation is naive in several aspects:

1-The only time Israel seriously took part in peace negotiations was in the Oslo accords (everything that came after, including Camp David 2000, was farces), and the PM was assassinated for it. It's Israeli fundamentalists who ruined it for everyone.

2-Israel actively funded Hamas, and keeps supporting them (they also knowingly created the current status quo) because they don't want Palestinians to have a representative who can negotiate for peace and a Palestinian state. The current division of Palestinian between Palestinian Israelis, East Jerusalemites, West Bankers and Gazans is an intentional part of Israel's Apartheid (or brutal occupation, take your pick) system, and they're not about to let it go away.

3-The West Bank, where Hamas has barely any presence, is currently being genocided (or ethnically cleansed, again take your pick). If the West Bank can't have peace, then everything about the continuance of the conflict being Hamas's fault is nonsense, also known as Israeli propaganda.

Also BTW, the blockade of Gaza started in 2005. That's before Hamas was elected.
