Redemption of Truth and Machzor HaGadol

At the beginning of Chapter 4 of Kol HaTor, we have the following:

א) תכלית הגאולה גאולת האמת וקדוש השם.  עפ"י דברי נביאינו ובאורי רבנו, תכלית עבודתנו בכלל, מלחמה בארמילוס ע"י קבוץ גלויות וישוב ארה"ק לשם גאולת האמת וקדוש השם, וזאת כוונת הנביא (ישעי' נ"ב) "גאל ירושלים" הנקראת עיר האמת. גאולת האמת יכולה להיות רק אחרי כל ביעור הקליפה של עשו הבא בצורת ארמילוס אשר כל שאיפתו היא שנאת האמת, וזהו עשו שונא ליעקב שהוא יסוד האמת, תתן אמת ליעקב, ותכלית גאולת האמת היא קדוש השם

A) The purpose of the Geulah is the Redemption of Truth and Sanctification of G-d's Name. According to the words of our prophets and the explanations of our rabbi, the purpose of our work in general is war against Armilus by way of Ingathering of the Exiles and settlement of the Holy Land in the name of Redemption of Truth and Sanctification of G-d's name, and that is the meaning of the prophet (Isaiah 52) "Redeemed Yerushalayim", that is called City of Truth.  The Redemption of Truth can be only after the burning of the klipah of Esav which comes in the form of Armilus, whose whole desire is the hating of truth, and that is "Esav hates Yaakov", which is the foundation of Truth, "Give truth to Yaakov", and the purpose of the Redemption of Truth is the Sanctification of G-d's Name...

It would seem to me that we are in the era of the fulfillment of this passage, and it is encapsulated by our current Machzor Gadol of 28 years.  The first half of the cycle (coinciding with the fall of the Klipah of the Left) will be the physical fulfillment of Redemption of Truth, the second half will be the "spiritual" side, if you would, the idea side, which can only truly commence after the Klipah itself is defeated.  As in all aspects of the Geulah, the physical side precedes the spiritual.  Redemption of Truth is crucial always, but its success depends on freedom from the servitude of the nations, which coincides with the beginning of Yemot HaMoshiach.
