@RSO,
“Can you name me ehrliche Yidden who said that nobody [alive] is worthy of it and it will be someone from the dead?”
For once I agree with you. I am not aware of, even among the Rebbes greatest admirers, a non Lubavitcher who said that. If you will cite Rav Aharon Soleveitchik, he said that he believed that the Rebbe was worthy of being Moshiach *before* his Histalkus.
