undeniably a nation

A nation is defined by four characteristics:

1. Population - A settled population
2. Territory - A defined territory
3. Government - A government
4. Ability to relate to other states - The ability to conduct relations with other states on a sovereign basis

Israel does not have a defined territory. Their borders have never been officially established. Using guidelines used by the UN they are not a nation. Even four is debatable given how many countries they've attacked in the last 12 months alone.
