I don't think that things are black and white here. But I have to agree a little.
Israel did become a nationalistic autocracy and has deeply corrupt leadership. Still, not doing anything when they were attacked on the scale Hamas recently did, would be just stupid.
The problem is that they should have kept the civilian casualties to minimum. Ideally under the amount of Israelis that died tho deflate grudges over time and show some degree of good will.
Then again Hamas has never shown such incentive. And differentiating between Palestine civilians and Hamas collaborators or members is not an easy binary task.
