The main idea of Israel is the idea of protection of individual rights for everyone in its borders-regardless of faith. This is displayed very well in the case of enemies of Jews that live in Israel that work to kill Jews and yet their rights are still respected unless they actually break some law. It is a degree of respect for individual rights that you don't see anywhere else.
At any rate the only way that I can see one can defend the state of Israel is from a libertarian point of view, of respect and protection for all people in its borders--even those that ought not to be protected.
There is something about the superorganism and the State that is interesting at least. All I am saying is that you can't defend any state from the standpoint of Hegel because I just don't think nationalism is that great of a principle. While people certainly choose their morality based on group identity but I see that as a negative thing. I think it is better to choose ones morality based on principles that are perceivable by reason.
