I’m quoting shmoolik 1:
“the three oaths are dependent on the nation of the world who will not destroy Yirael if they try there is no obligation on us to comply
the UN in 1947 allowed the state to become so there is no revolt only after did they oppose
NK and their like will be like Korach and his eida when the Moshiach comes”
1) The oaths were between us and Hashem, and between the nations and Hashem. The fact that the goyim broke theirs does not mean we can break ours as well. To compare – if your neighbor is mechallel shabbos, does that mean you can be mechallel shabbos as well?
2) The “umos” has nothing to do with the UN, but with the people that live(d) in the land (before us – ie, the Arabs). The UN doesn’t have any status in halacha. What counts is what the people who live in the land think about it – and they obviously did not agree to it.
3) I’d rather say that about the Kahana followers, but fact is that they already are exactly that right now.
