Just Emes:
Did Rav Moshe write (against the earlier poskim) that the oaths were not halachic and not applicable liMaaseh?
Did Rav Moshe write that it’s muttar to be oleh biChoma?
Did Rav Moshe write that it’s muttar to be madchik haKeitz?
Did Rav Moshe write that liUmiyus (Nationalism) is, CH”V, part of the Torah?
Did Rav Moshe write that liUmiyus is permitted (to be grafted on to the Torah)?
I’m not at all convinced that it’s “just a history of the shittos haposkim” without answers to those specific questions (and more).
Again, even the Zionists Rabbis try to (unsuccessfully) find teirutzim for the three oaths, like the San Remo conference, et al. According to your story, they should have just asked Rav Moshe. Not to mention the vehement opposition of gedolim earlier than Rav Moshe, such as Rav Elchonon who called Zionism A”Z, Rav Aharon Kotler, Brisker Rov who called the State the Satan’s greatest accomplishment since the egel, etc.
I find this bizarre, as much as I trust your screen name.
