The old answer is the best one

One of the questions I’m most often asked is about Jews and Israel. In fact, the question of what right Jews have to live in Israel is one that we are all asked repeatedly, by both friends and foes. Some point to historical documents like the Balfour Declaration or the League of Nations. More recently, some have referenced Israel’s defensive military victories of 1948 and 1967 as justification of legitimacy.
Despite these responses from various platforms, the question is still being asked, our legitimacy is still challenged, and our identity is often questioned. And this isn't just a rhetorical issue. When one’s identity is under question, so is their self-confidence—and this can also impact how they are treated by others.
So, perhaps it is time to return to the basics, back to the beginning—yes, the very beginning, in Genesis. This week, we read how G‑d said to Abraham, “I have given this land to your descendants” (Genesis 15:18).
When G‑d promised the Land of Israel to Abraham, and his son Issac’s descendants, the land became—and remains to this day--the inheritance of every Jew, not subject to negotiation or trade. It is solely G‑d’s promise to Abraham that constitutes our unshakable connection to the land.
On numerous occasions, when speaking with Israel’s leaders and in his public addresses, the Rebbe expressed his belief that confidently and unapologetically articulating this claim would earn the respect of the international community. The Bible, revered by billions around the world, commands respect; additionally, even those who do not share this belief will appreciate our conviction in it. The Rebbe argued that basing the Jewish claim to the Promised Land on treaties, military victories, or diplomatic agreements can, in fact, undermine respect for the legitimacy of our claim in the eyes of other nations. Only when we stand firm in our beliefs and traditions can others respect us as well.
When we are more educated and do stand firm, we are also a blessing to others for all the good needed in their life, as G-d said to Abraham “through you all the nations will be blessed,” and “I will bless those that bless you.”
