You don't understand that a people who suffered a catastrophe where 25% (?) of their global population was destroyed might have a fierce yearning for their own homeland?
According to Nazi ideology it was precisely because the Jews had no homeland that they owed no allegiance to any state. And the Nazis weren't uniquely anti-Semitic either. So what would you have the Jews do? People complain when they don't have a homeland and now complain when they do.
(I realize that this isn't what you'd say Mr Whizz. I'm just expressing a point of view.)
There was also the "complicity" of the European Jews, through Jewish Councils, in their own destruction to consider*. Is it surprising that they are keen on defending their piece of the globe now; against all comers and all non-Jewish residents?

Or is this a myth?
Still, I'm just trying to think myself into the mindset of the average Israeli, here. Probably unsuccessfully.
