The best place to consider that question would not be Brussels, but Tiraspol, the capital of the entity that calls itself the Pridnestrovian Moldavian Republic, or Trans-Dniestr. This territorial sliver with a population of a half-million emerged in the early 1990’s, after the dissolution of the Soviet Union (population almost 300 million), when it broke away from the Republic of Moldova (population four million), which had separated in the 1940’s from Ukraine (population 50 million).
