Three Falls

Din becomes Chesed when the Sitra Achra falls. The Sitra Achra fell after the second world-war and with the rise of the State of Israel. Because of our sins, the Sitra Achra recovered and stole תצ"ט of the left and onwards. After the next fall, ז"ך of the left will bring Chesed, but right after that, disaster may yet strike. Some will revolt against Moshiach, and the Sitra Achra will attempt to steal Din after seven years. The attempt may fail in the merit of Yisrael, and that will be the end of Ruach HaTum'ah. Should Yisrael's merit not suffice to foil the attempt, this would prevent the third Tikkun of Atik Yamim, which cannot be. The cost will be great, and there will be yet another war, which will cause the end of the powers of Tum'ah.

שאלו תלמידיו את רבי יוסי בן קיסמא: אימתי בן דוד בא? - אמר: מתיירא אני שמא תבקשו ממני אות. אמרו לו: אין אנו מבקשין ממך אות. - אמר להם: לכשיפול השער הזה ויבנה, ויפול, ויבנה, ויפול, ואין מספיקין לבנותו עד שבן דוד בא

(Talmud Bavli, Sanhedrin 98a)
