CA/RW: So what? The point that was advanced here was that the Shalosh Shavuos was nullified because the United Nations gave permission for a Jewish State. If that’s the basis to nullify the Shalosh Shavuos, then on that basis the nullification is only applicable to the Jewish zone and not to the Jerusalem (international) zone or to the Arab zone, since no permission from the UN (or from the British) was ever granted over those territories.
A later war isn’t a basis to nullify the Shalosh Shavuos.
