Likewise, while we do know that the Danubian Whatever has aspects of Societism, we also know that the Societists censored the statement by Sanchez that Vienna was on the right track with its reforms. So in fact we have strong evidence that the state will be on the Diversitarian side.
Presumably, Societist whatever-Danubia-is-called is TTL's version of the PRC.
And Turkey would be a disastrous fit for Societism. How exactly would you merge Orthodox Christianity, Sunni Islam, and a sprinkling of Judaism? In more practical terms, how would any plausible state have the strength to tell Arabs, Kurds, Turks, Armenians, South Slavs, and Greeks to even out their folkways and languages? To even get started you'd need something like full-on support from a firmly Societist Russia (just for example); otherwise it would just be an exaggerated Young Turks situation - the attempt at conformity would just make the already delicate polity rip along the seams. In which case you'd still have a Diversitarian Balkans between the two Societist powers you posit, and Turkey would hardly be a neighbor.
No, the Ottoman Empire (or whatever comes of it) would be much better suited to Diversitarianism's live and let live attitude. Actually, the institutionalisation of intergroup hostility the anti-Societists use - playing out tensions in a controlled fashion - would probably be an excellent way to hold the place together.
Firstly, we don't know how big this Societist Ottoman state is - it could just be an oversized Turkey for all we know, with the rest of the Empire having fallen away. Alternatively, Islamo-Societism (or whatever it's called) may not be that similar to the version used by the soon to be former-UPSA.
What is Societism's take on religion, anyway - is it going to form a neo-proto-Indo-European faith, or a mishmash Abrahamic one, or something entirely else. State-sponsored Atheism perhaps, on the grounds that religion fosters division? (Given that Thande is a person of faith (Methodist, IIRC), and that Societism is supposed to be (mostly) based on things he really,
really doesn't like, and all...)
If anything, we just found out mainland Italy will go Societist, and probably work diligently to annihilate the many dialects. Given the OTL relationship between the region and southeastern South America, that wouldn't be entirely surprising.
Actually, the previous update has Italy as part of the Diversitarian block of European nuclear powers. If anything, a Diversitarian Italy would probably emphasise the distinctiveness and diversity of its regional dialects,
of which there are many.
Also, my views on Russia is that it does something similar to the Russia in Decades of Darkness, in that it federates (some) of its satellite states, and spins off various provinces with a large non-Russian/East Slavic population as autonomous states.
In the former case, one could include Georgia, Crimea, the Kazak state, Courland, and possibly Lithuania and even greater Finland. The latter category would include places like Moldavia, Chechnya, Dagestan, and the Tartar, Bashkir and Yakut majority areas, etc.
