HaLeiVi:
“the Rambam actually does not hold this way.”
Please stop inventing your own Torah.
The Rambam wrote Mishneh Torah as his compendium of the oral law.
“Our Sages taught: “There will be no difference between the current age and the Messianic era except the emancipation from our subjugation to the gentile kingdoms.”
(Mishneh Torah, Kings and Wars 12:2)
Furthermore, Rambam wrote:
“If a king will arise from the House of David…”
(Kings and Wars 11:4)
For a king to arise in the Land of Israel, it would be necessary for a large number of Jews (but not all Jews) to return to the Land of Israel PRIOR to arrival of Moshiach.
Thus the invented notions of Satmar / NK, where Jews only return to E.Y. after Moshiach arrives, were rejected by the Rambam.
