This is a question for posters on all sides of this “machlokes:”
If following years and years of an enemy government occupying the Old City of Yerushalayim and not allowing Jews to even enter, a non-Jewish army miraculously defeated our enemy, took control of Jerusalem, and let Jews return to the Old City of Jerusalem to live and serve G-d there, would we be celebrarting that day as Yom Yerushalayim? Is there necessarily a relationship between Yom Yerushalayim and the Medinah?
