R’ Yosef Eliyahu Henkin zt”l wrote the following letter:
I was shocked to read in Chomoteinu of Cheshvan 5719 the slanderous notion that we are required to give our lives (limsor nefesh) to frustrate and resist the efforts of the State of Israel in its struggle against those who would rise up against them. This was stated as a p’sak din based on what we learn that Israel is restricted from rebelling against the nations (Ketubot 111a)…
Now all the rabbis who were opposed to Zionism and the establishment of a state took up that position until the time that it was officially founded. Once the state was declared, anyone who plays into the hands of the nations of the world even where there is no imminent danger, is clearly a moseir and rodeif. All the more when there is danger to destruction of life in so doing… Surely, those who recently emigrated must be very weary of the state’s efforts to strip them of their Torah way of life, but to proclaim that anyone who aids the state is a rodeif, well such talk is the severest form of redifa.
Clearly, R’ Henkin felt that after the state of Israel was established, things changed. Not only that, but he even said those who oppose it are considered rodfim!
