This question would be much more answerable with some specifics. Specifically (excuse me, my historical knowledge is lacking),
how did the Jews of Babylonia aid the revolution and (more importantly)
how are you proposing they aid a future one? Asking whether Jews are allowed to vote for caliphs for Congress is very different from asking whether Jews are allowed to support caliphs' assassinating the Cabinet. I think that this question is unclear (or too broad) as asked, and I suggest you
edit it to something more answerable. —
