Answer

The question of whether there is a commandment to live in the Land is subject to dispute (famously, Maimonides does not count it). As I understand it, this has nothing at all to do with time—whether in the past or today.
According to the views that there is a commandment to live in the Land, simply speaking this is a commandment incumbent on the individual and is not connected to sovereignty; therefore, the commandment applies within the borders of the Land of Israel as defined by Jewish law. According to Nachmanides, there is also a commandment to conquer the Land, and that is, simply speaking, a communal obligation.
