HaKatan: The conditions they set shouldn’t matter – they clearly felt it wasn’t a violation of the oaths.
With your definition of mesorah, you may be correct. There was no mesorah for Zionism. Don’t forget that there’s no mesorah for electricity. There’s also no mesorah for banning the internet – how dare people rally against it when there’s no mesorah to do so! There’s no mesorah regarding pretty much anything that didn’t exist at the time of Kabbalas HaTorah! New situations arise all the time, and Rabbonim come up with a derech based on halachah. They may not always agree, and that’s where machlokes comes in. Zionism is one such case. Claiming that views held before the founding of the state of Israel are all valid and unchanged after the founding is not proper. As circumstances change, the application of halachah can change, because the psak may no longer fit the circumstances! R’ Soloveitchik clearly had reason to hold what he did, and his shoulders were sufficiently wide to carry such responsibility.
Your insults against him are pure lashon harah. I honestly can’t believe the mods let them through.
One last question – I’m honestly curious to know, what is your opinion on chassidus? There was no mesorah for that either – the Besht went against the established practice of Judaism when he started it. That’s why many were against him. What do you think about it? Does Chassidus have a valid mesorah?
