All of those things can be argued to fit the Rebbe.
Disagree strongly.
But am totally not interested in getting into this argument.
If you learn this Rambam like you learn all Rambams, you would never say that the Rebbe fits the description.
If you hold the Rebbe is Moshiach and want the Rambam to shtim with that belief, you can drey the Rambam like a pretzel and have it shtim.
I wish there would be intellectual honesty on both sides of this argument.
I believe that after learning the Rambam in depth without preconceptions - there are 2 conclusions:
1. It is very mashma that Moshiach can come from the dead, as long as he wasn't killed. (I might be the only Litvak alive who will concede that point
)
2. Nobody since Bar Kochva came even close to being Bechezkas Moshiach. Probably nobody even fulfilled 1 of the tnaim!
(If your me'aiyn in the Rambam, you'll realize that the mekor for e/t he's saying was the story of Bar Kochva. So when you try to figure out what each tnay means exactly - think Bar Kochva)
