I mean up till today I haven't heard a noble reason to kill off people in a the second WW and neither have I found a reason to create Israël that made me smile and say "well wow that is really a good reason to do that in the Palestina".
Things often don't happen for "noble reasons".
Without claiming to say everything that matters on the issue:
First it's not that some European decided first that it's a good idea to give the Jewish people Isreal and later all those people went to Isreal.
It was a decision made by the Jewish people to settle in Israel for religious reasons (Zionism).
There was also the "never again"-zeitgeist. They decided that they should fullfil their prophecy, because they think that getting their own country protects them from racism (very ironic if you consider that it easier to kill a lot of them today by throwing a atom bomb on Isreal).
It's also America that pays the money for a huge part of Isreals military that allowed Isreal to not get wiped of the map by it's neighbors.
Why does America pay that much to Israel? America has a strong Jewish political interests.
And they have the big holocaust argument that also plays into American politics.
They are also a huge voting block that votes based on the Isreal position of candidats.
Why does America has such interest and not say France? The holocaust reduced the number of Jewish people in Europe.
Why did the Nazis made the holocaust? Because of strong Jewish political interests that they didn't like in Europe.
I don't think that you can understand the middle East without understanding the holocaust.
There are also other issues involved in the middle East but the holocaust is a central issue.
Do you really think that they explain the why at all schools in Europe? Forget it.
No, I don't. But I still think that when people don't know a lot that it's good when they know a few important things that played central roles.
One of the reason that Bush gives for invading Iran is that Iran is denying the holocaust. You at least have to know what the holocaust means to evaluate a argument like that.
I hate the fact that you don't have a seperate plural "you" in English. The part about being ignorant was more about being ignorant as a group.
Since America has democratic elements, it counts a bit what it's citizins think. If a lot of people demostrate for something where they understand nothing about the issue it affects politics (sometimes).
