If Israel had to rely on a human rights platform, it would not have come into existence in the first place as war with your sworn enemies and detractors has nothing to do with human rights i.e nice guys finish last or don't finish at all. The attacks on Israel's existence throughout the years is further evidence of this. And as to you final thought, there may be a tradition of Jewish atheism but it has nothing to do with Judaism whose central theme is God and Torah. In fact, without being born to a Jewish mother, how could you tell that these atheists are even Jewish. No connection to the central precepts of Judaism. No observance or practices even remotely connected to Judaism. A complete accident of birth without any further relationship, practices, observances of Judaism.
