AAQ said – Are we 100% sure that Moschiach will run a monarchy?
It certainly seems that way from all of our sources. Although in a genuine Torah Malchus, the King isn’t above the ‘constitution’ – i.e. the Torah, so Jewish מלכות is ‘constitutional’. Even when Izevel wanted to ‘help’ Achav confiscate the vineyard of Navos, she had to concoct an elaborate plot with false witnesses to give the appearance that he was really חייב מיתה, and Achav couldn’t simply take it by force. And that was by Achav, who obviously wasn’t a big Tzaddik.
AAQ – Rambam says there will be no difference except that Yidden will not be governed by others.
According to Rambam there will be no difference in the physical order of nature (literal וגר זאב עם כבש for example). There will be huge differences in society both within the Jewish people and in the world at large compared to what we are used to. Everyone will have an iPhone without any filter, because there simply will be no more shmutz in the world. When the Sanhedrin will be Mekadesh Rosh Chodesh, or declare an Ibbur year, the Calendar App will automatically update. Moshiach’s Shiur will be broadcast live on all of the telecommunications channels in the world. India and Pakistan and whatever will be left of Russia and Ukraine will be best buddies… Bibi will probably go into voluntary and honorable retirement… All this aside from the Beis Hamikdash with Korbonos and Aliyah Laregel etc. So a lot of stuff is definitely going to change for the better… במהרה בימינו אמן.
