Btw regarding a sign, during the period of the gulf war the Rebbe referenced the yalkut shimoni talking about how in the year Melech HaMoshiach will reveal himself, the Persian king will start up with the Aram king (the Rebbe saw this as the American king) and the Jews will be scurrying in fear (as they were in light of the threats of Saddam Hussein- which only recently did we see just how big they were), and Moshiach will tell them, humble ones, the time of your redemption has arrived!
The Rebbe told everyone who asked there’s nothing to fear and you should not leave EY, and indeed the war turned out the way the Rebbe said. And he was the only one saying so, publicly assuring everyone. Yeah that was one of the things I was talking about in 5751
