In his address of Pesach Sheini, 5738 (1978), the Rebbe spoke of the need to settle the entire Land of Israel, explaining:
It is true that “the Guardian of Israel neither sleeps nor slumbers,” but G‑d wants people to also act within the framework of nature, at least with the minimal effort required to move one’s little finger. This is what He teaches us in the Torah: When the Jews hear that gentiles want to come to a city “to take straw and chaff,” if it is a city from which it “would be easy for them to conquer the land,” the Jews are to “go out and face them with weapons and even desecrate the Shabbos.” In such a case we have a promise that the pressure placed upon the Jewish people to concede, will be nullified — as we have seen many times when we stood fast.
The Rebbe spoke in a similar vein in his address of Motzoei Shabbos Mishpatim mentioned above:
All of the anguish and suffering which the Jews experience as a result of the negotiations is totally unnecessary. When they act swiftly and quietly, all the pressure will be forestalled, because the nations will see a fait accompli, an irreverable act of the Jewish court that the Land of Israel is an everlasting inheritance of the immortal nation.
The Rebbe adds that not only will the nations cease their pressure, but will ultimately even assist us, as the Rebbe says on Motzoei Shabbos Chaye Sarah, 5738:
Settlement of all parts of the Land of Israel will even affect the nations, to the extent that they will even assist us. They will also “feel” (since their mazal will see) that the existence of Esau is only for the purpose of helping Jacob. This will be a preparation for the ingathering of all Sons and Daughters of Israel — shleimus haAm — to the whole the Land of Israel, in the coming of (and through) Moshiach, after which “G‑d will extend your boundaries” — and the Land of Israel will be expanded, with the addition of the lands of the Keini, Knizi, and Kadmoni.
