In our day and age, after G-d has vented His rage with the destruction of the Holy Temple, and after all of "our deeds and actions throughout the duration of exile," and after all the decrees of oppression and persecution - may Hashem save and protect us from them - the Jewish people have suffered throughout the long and difficult final golus, particularly following the Holocaust of the very last generation, the process of refinement and purification has, without any doubt, been achieved in full, "more than enough and even too much."
Consequently, the current "siege of the Babylonian king" has acquired an exclusively positive connotation, one that is visibly and manifestly good, even to eyes of flesh. In the words of our sages (Yalkut Shemoni Yishayahu remez 499): The Holy One Blessed be He says to Israel, "My children have no fear. All that I have done I have done exclusively for you... the time of your Redemption has arrived."
The emphasis of our generation should be placed on the support of G-d to those who have fallen, to strengthen and encourage the Jewish people, emphasizing particularly the support and encouragement acquired through faith in the coming of Moshiach and the implicit trust that "behold he (our righteous Moshiach) is coming." This should be accompanied with enhanced preparation for his arrival by way of Teshuvah and observance of Torah and mitzvos. To paraphrase the pronouncement of the Previous Rebbe, the leader of our generation: "immediate Teshuvah, immediate Redemption." "Return, O, Israel, unto G-d your G-d; prepare yourselves and your family to greet our righteous Moshiach, who shall arrive soon, in the most literal sense." (Hayom Yom 15 teves).
