The Rebbe Rayatz (sixth Chabad Rebbe, father-in-law of the Rebbe King Moshiach Shlita) said already in his time (in 5689/1929) that we have finished the work that needed to be done in the exile, and all that is left is to “polish the buttons”. Now, decades later, we have certainly finished “polishing the buttons” as well. In fact, too much polishing ruins the buttons. G-d must rush to bring the Redemption through Moshiach NOW!
