No im not saying the state needs to be ethnically pure, only that its rule needs to be a jewish-prioritized rule (kinda like modern day israel is)... in other words, there is no evidence of a country that was jewish rules by right.. only countries of mixed ethnicity with no one ethnicity being the ruling ethnicity.
If we look at every time period there was either no clear side ruling and it was a mixed culture and mixed ethnicity (helenistic period) .. or it was ruled by someone that was of neither group (the romans).
