I’m reading the Chayenu (Chabad) commentary on the Torah portion of Ki Seitzei (Deuteronomy 21:10–25:19):
…The Jewish people as a whole are to serve as an idealization and inspiration for humanity at large. Analogously, God set the Land of Israel apart from the rest of the world — by virtue of its special status in Jewish law and observance — in order that it serve as the example of what the rest of the world should aspire to…
The..second phase in the process is for the Jewish people to undertake voluntarily to expand the borders of their state, thereby increasing the territory in which the special laws of the Land of Israel apply. In this way, they gradually increase the proportion of the world that exemplifies the ideal of being a true home for God…
It is clear from the Book of Genesis that the various geographical divisions of the world were assigned to the nations suited to inhabit and develop them, each according to its unique cultural disposition. By what right, then, can the Jewish people appropriate territory apparently not intended for them?
…If a neighboring nation, witnessing this model of what a Divine home on earth could be [after the Jews turn Israel into a “utopian model of holy living”], chooses not to participate in this vision (by accepting the Torah’s rules of life for non-Jews), it has forfeited its right to steward its own land and citizenry.
From the 2012 Chayenu on Torah portion Bereishit:
True, the Torah does also contain God’s instructions to the rest of humanity, but these instructions are presented solely in the context of the Jewish people’s responsibility to impart them to the non-Jewish world…
God created the world as a “lower realm” with regard to Divine consciousness — initially devoid of it and even antagonistic to it — intending that humanity then introduce Divine consciousness into the world and ultimately fill it with this consciousness. As a result, Gold would become “at home” in this physical world…
The tool God gave humanity to enable it to perform this feat is the Torah. By living life according to the Torah’s instructions, humanity would be able to transform a world initially antagonistic to Divinity into one conducive to Divinity. The drama of creation thus required three elements: the world, the human race, and the Torah, serving respectively as the setting, the actors, and the script.
Chayenu on Torah portion Chayei Sarah:
Sarah participated in Abraham’s great enterprise, helping him spread his message among the world’s women with the same undiscriminating eye he used toward the world’s men. When Isaac was born, however, and they were entrusted with raising a child who would have the moral strength and vision to carry on their Divine mission, she realized that this universalism would have to be tempered by a discerning particularism…
A family or a people, like any living organism, must have well-defined borders.
Everything I believe can be found above. All the rest is commentary. Go and study.
