““Who is worthy of being moshiach?”
One person I know who is not. Rabbi Menachem Mendle Schneerson.
On that note, what’s incredible is that the Lubavitchers actually think that non-Chabad believed that Rav Shach was Moshiach. lol. Nothing could be further from the truth. No one in their right mind ever believd such a thing about any litvish gadol. Its only nutbags like Shabsai Zvi Yemach Shemom and chassdic movements that declared their leaders the Mesaiah. They also said the Ruzhiner was Moshiach – every one of the RUzhiner rebbes. Breslov, and many others. Check it out. Chabad wasn’t the first one to declare a Moshiach Sheker.
