To clarify, the whole “sharing the burden” nonsense (which the IDF itself does not agree with, as they don’t want Chareidim, at least not ones who aren’t prepared to convert to Zionism) is simply another (very serious) Zionist shmad tactic.
I have mentioned Rav Elchonon’s and Rav Chaim’s holy words many times on these boards. There is no known dissent among those accepted in the general Torah world.
So it seems pretty simple to me. Chareidim (and their descendants) who preceded the Zionists are off-limit to the Zionists regarding shmad, the army, denying permission to work, etc. On the other hand, those who, for whatever reason, choose to join the State of Israel and agree with its policies, certainly have that choice.
