Which start? There are so many in that conflict.

So did the other sides. For outsiders, it's very hard to know what's really going on in that region; so many history, so many details, so many emotions, so many abuse and killing... It's a chain of reactions and counter-reactions which is going for over a century. Don't assume that everyone can know everything.
Israel was also very good at manipulating the Western World and building on their collective guilt. Even if a politician knew what was going on, it would have been political suicide to speak out too much about this. Even now, it's a delicate topic. And people still blindly spreading hate against all Jews, while it's mainly the fault of some factions, is also not really helping the cause here.
> - I don't hear any apology about the above
Apologize for what? At the end of the day, there are all trapped in a situation where they have very little control.
