Who cares if the state was founded be’issur or be’heter? What’s the nafka mina? If it’s beheter you must say hallel on Yom Ha’Atzma’us but if it was be’isur it’s assur? If it’s behter you must ignore all the religious problems with the state but if it’s be’issur you must ignore all the good it does for Yiddishkeit (like funding yeshivos and opening up the borders of Eretz Yisroel for Jews worldwide)? If it’s be’issur you must join Neturei Karta and support Arabs who want to turn the Land of Israel into an Arab state?
I dunno, I think this argument is theoretical at best. Whether be’issur or beheter, the state is here. The question is what do we do now? And the answer is, whatever is best of Klal Yisroel, regardless of how the state was founded. It’s time to stop arguing about the past with an argument that has absolutely no practical ramifications, and start focusing on the future, how can we influence the current state of events to benefit Klal Yisroel?
