Where Does It All End?

I take it back. As mad as I may be at the rest of the world, even I can't shut myself away from what's happening in Gaza. It's terrible and it's wrong. But it does make me wonder whether the holocaust really was so horrific. Whatever I've ever read or heard or studied or known about the holocaust always made it seem like it was this unthinkable evil, and I believed it and sympathized, and I still do. But what I am entirely unable to understand is; how a race of people, who have apparently survived such a cruel example of human nature, could treat others with the same inhumanity just a few decades down the line? Maybe it's some form of Stockholm Syndrome, you know. Identifying with the abuser and all that, and Gaza is just a manifestation of it.
