In his address of Shabbos Parshas Matos-Masei, 5749 (1989), the Rebbe said:
There are special demands placed upon those who work for the community, since they have an added share of responsibility in rescuing the general public from danger ... and especially community leaders in the Holy Land, “The land upon which G‑d’s eyes continually rest from the beginning of the year until the end of the year.” Such leaders have superior capabilities which must be taken advantage of in full.
In particular, this includes their duty to influence the government not to compromise, G‑d forbid, on even one inch of our Holy Land. This is because the Holy One gave it to the Children of Israel, so that they may dwell there as free men, even prior to the redemption. “There is no true free man, other than one who is involved in learning Torah,”1 in true contentment and security. In this context, we will merit to immediately enter and inherit the land, with the full and complete redemption by our righteous Moshiach.”
