I guessed they could nowadays be like this, by the best chances. I might be wrong though:
Estonia: Would make up part of the Nordic countries, although maybe with some German hints. Its character, relatively low levels of corruption, drive for progress and sense of orderliness gets them the closest to the values deemed to define Nordic societies.
Latvia: Could be part of the Nordics as well, dependent upon discovering what causes their high levels of corruption and other deviations that distance it from Nordic societies. Otherwise, could be similar to Slovenia or the Czech Republic, had they not been Communist as well.
Lithuania: Could be similar to Poland, had it not been Communist.
