Perhaps this is where we can find some common ground. Your initial statements were a bit more murdery. I have no doubt about what you're saying about the Israeli people today. I believe that it will take a program akin to Germany's denazification (improving based on what we saw in Germany) to get things straight.
I believe people are taught to hate and can learn to not hate. It's not easy nor is it ever 100%, but it's possible. Humans are the most capable species on the planet when it comes to learning and adapting.
Unfortunately, I'll admit, most of my life I've seen a drive towards hate but I believe this is politically intentional on the part of the ruiling class.
