SQUARE_ROOT:
You make great points above.
One other point that must be made – even IF the Three Oaths are halacha, they were never violated by the creation of the State of Israel.
The UN General Assembly voted by a majority vote in 1947 to allow a Jewish state in part of Eretz Yisrael.
The Jewish Leadership accepted the UN Plan.
President Trump placed the US Embassy in Jerusalem.
Thus it seems that the only Jews who are now violating the “Three Oaths” are Satmar and N.K.
