Jerusalem is the very heart of the Jewish Nation, People, Religion and Land, and this has been for thousands of years. And to repeat something very crucial, the Jewish religion, People, Nation etcetera have existed thousands of years before the advent/invention of Christianity, Islam, the USA and the United Nations.
We celebrate Chanukah because it commemorates the Jewish victory over the Ancients Greeks, who no longer exist. They tried to exterminate, defeat us, and they failed. What appeared to be mighty was actually weak. This template has repeated many times in Jewish History.
When the "experts" think we're down, we rise again. Here we are in the Modern State of Israel defying the Arab armies and their many supporters. Two thousand years of exile, and we are stronger than ever, bli eyin haraa.
It really doesn't matter what the world thinks of the Jewish and Israeli rights to Jerusalem. The last and possibly only time Jewish sovereignty in Jerusalem was after King Solomon built the very first Holy Temple. And maybe only when we build the Third Temple will we again get the acceptance that will bring the Moshiach. That's how it seems to me. We shouldn't fear. It's time for a Nachshon, the brave fleeing Jewish slave, who stepped into the water and caused Gd to make a dry passageway to facilitate the Exodus from Egypt.
Gd willing, speedily in our days....
