curiosity: I am burning the midnight oil after melava malka…
First of all, you cannot- CANNOT- use the sholosh shevuos as “halacha”. It is not mentioned in ANY of the Poskim, so whoever tells you that it is “halacha’ is plain wrong. It is aprt of aggadah and hence, it has less authenticity. Secondly, it does not say anything about “taking the land away from to build a state on it”. All it mentions is that “shelo jaalu bechomo”-they should not go up (to israel) with violence . This clearly was not the case as far as the medinah- it was given back to us by the Balfour declaration and the United nations resolution .
Lastly, the fact that it is “non-Torah observant’ (your words) is irrelevant- look at how the kingdoms of Jehuda and Yisroel were. Many of the kings were much worse than our present governemets in israel.
But all of the above is just a debating point- the medinah exists, more than six million live there and we must support them.
