The Role of the Leader of the Generation in Redemption
...It may be said that the resolution and announcement of the leaders of the nations of the world on the eve of Shabbos Parshas Mishpatim concerning the condition and situation of "they shall beat their swords into plowshares" is an effect of the resolution and announcement of "our kings, the Rabbis" that "Behold he (the king Moshiach) comes." [The situation today] began with the legal decree of my sainted father-in-law, the leader of our generation, that we have already completed our work and Divine service in the course of the exile and we are already prepared to greet our righteous Moshiach. It then continued through the legal decree of the rabbis and authorities of the Jewish people that the time of Redemption has arrived, "a king from the house of Dovid will arise... it is presumed [b'chezkas] that he is Moshiach" until the situation and position of "behold, he is certainly Moshiach [vadai]."
[These are] legal decrees "from Sinai," which extend into and penetrate the barriers of the world as well, to such an extent that the leaders of the nations resolve and announce voluntarily (and "in their courts" for they have the force "the law of the country is the law") concerning the situation and position that "they shall beat their swords into plowshares."
