- There is only one Israeli citizenship. Jews have it. Israeli Arab Muslims have it. Israeli Arab Christians have it. Druze have it. It's the same.

Is there discrimination, in all directions? Yup. The world is a tribal place.

But you should move on from that "tiered" thing. I live here. I have been doing a project with Arabs for the last two weeks. We have lunch together most days. Move on.

- Constitution -- You clearly have not read the constitutions of Syria, Saudi Arabia, or many other countries. Ethnic groups are all over the identities of most of the world's countries.

- Automatic citizenship - How narrow do you define this? African Americans can go to Liberia and other countries of Africa. Until just twenty years ago or so anyone with a German grandparent could automatically get German citizenship. If you are Cuban you can get American citizenship. Are you thinking this through?

- NPT, I am not sure anyone cares, but this is very different than your other topics.
