Assurnet, FYI already in Morocco their was massive secularization due to the influence of French culture (according to Rav Aviner this is why their rabbis banned marriages with converts – well-to-do Jews were pressuring them to “convert” French women with whom they fell in love). In fact, religious immigrants were sent to religious settlements as per the agreement between the Mizrahi and Mapai. I have known more than one personally. In any case, you are living in the past. Today, Israel is fast becoming more religious. If the religious parties could unite and present a comprehensive (as opposed to sectorial) program they would definitely form the government.
HaKatan, even if the Three Oaths once applied they no longer apply. I have proven this beyond the possibility of any contradiction many times here.
