With all talking past each other, there are some statements here that look like real debate!
Avira > The balfour declaration (and even the UN partition plan) are irrelevant because when the zionists took over, the british were no longer baalei batim on the land.
This is very brisker for me. Could you unpack this in detail step by step? From my simple reading, there were several steps:
(1) initial zionist yishuv, somewhat supported by a small number of rabonim, but no others,
(2) Balfour declaration – that made further arrivals not violating shvuos as they came with permission
(3) state declaration by those who already arrived – not by shvuos – it is just a declaration, not arrivals and with UN permission
(4) later arrival from DP camps, arab countries, USSR – all according to international laws
where is your analysis different?
