Good point about the nation-state matter. For hundreds of years after Abraham, it was a family. While his family became Israel after the Exodus and took on the organization of a nation, which God HAD promised to him, it doesn't then follow that what we see now is that nation.
Netanyahu himself isn't an ethnic Jew, a fact that was used against him several years ago in Israel by his political opponents and that he weakly disputed. What we're looking it is a political organization that wraps itself if this so-called Jewish promise, but that's just propaganda since not a one of them can prove they descend from Abraham.
