Reading between the lines here, although ITTL it seems that Russia is being generally reactionary it seems that the left is getting off lighter than IOTL. It seems that with the Narodniki being (marginally) more successful we don't have them turning to assassination and that the Russian state is busy stomping on minorities and peasants so there's not as much repression to go around for the leftists in the cities. Am I on the right track or reading too much into things?
You're on the right track. Life for the urban left certainly isn't sweetness and light - leftists have to be very careful to avoid imprisonment or police violence, and any organizations have to stay underground - but the Russian state has higher priorities at the moment. Not to mention that the government is running a crash industrialization program, and it would be a bad idea to kill off all the skilled workers.
This probably means that, come the war and its aftermath, the "median leftist" in Russia will be incrementally less radical than in OTL.
Also just how thorough was the ethnic cleansing in areas like the north side of the Caucasus? Are the Chechens gone?
They're not all gone; some of them are holding on in the mountains, where it's very hard for a nineteenth-century army (or even, as we've seen, a late-twentieth-century one) to rout them out. The Chechens in the cities and towns have been expelled, though.
Very interesting to see what this is doing to the demographics of Anatolia and the Balkans. It seems that the Ottomons will hold on to a good bit of land in the Balkans and have a strong demographic position in Anatolia but there seems to be some foreshadowing that they'll lose the Arab provinces sooner or later, but maybe I'm reading too much into stuff...
They may lose the Arab provinces, but then again they may not. What will have to happen eventually is for the Ottomans to sort out their nationality issues, which will lead to them becoming a different kind of empire, but exactly how that will play out is still up in the air.
I'm surprised the Ottomans don't try to simply expand the number of seats on the Bank, but I can see the problem.
Or just squish the liberals through extra-constitutional means, although I guess that things are precarious enough in the sprawling empire that they don't want to upset things.
Messing with the central bank would send the empire's credit ratings into the toilet - one of the key reasons why the empire was able to avoid default was the creditor nations' trust in the bank's professionalism. The creditors, BTW, feel much more at home working with the liberals, many of whom were Western-educated, than the conservatives.
Also, changing the number of seats on the bank's board of governors would require a constitutional amendment, which the reactionaries aren't strong enough to put through.
Squishing the liberals extraconstitutionally would be a very risky proposition - they may have lost the election, but they still have powerful supporters in the bureaucracy and the army, and they control the mob in the capital. Also, the constitutional order has lasted long enough, and produced good enough results in terms of economic growth and military victory, that even the moderate conservatives have been reconciled to it. It's easier to negotiate with the liberals, especially since they (the conservatives) are negotiating from a position of strength and can get
most of what they want.
Two other points which occur to me: you might see many Muslims from Russia end up in the USA. Do they get treated as whites?
Some would probably go to the USA, but I don't know if there would be "many" - the Ottoman Empire is much closer, and the Russian Muslims have historic and religious reasons to go there. I suspect that those who choose the United States would be a relatively small group, skewed disproportionately toward the urban and educated, and that they'd fare much like the turn-of-the-last-century Bosnian Muslim immigrants of OTL - in other words, that they'd fit in pretty well, and there wouldn't be enough of them to get on the racists' radar screen.
They won't go to South Carolina, though - the Islam there is a bit beyond their comfort zone, and they'd be looking either for jobs in the industrial north or homestead land out west.
Secondly, I'm a bit concerned about the rise of Arab nationalism. Why is there any rise in [TTL]? The Ottomans are successfully defending the Muslim world against hostile Europeans; if anything I'd expect stronger Pan-Islamism.
According to Kimmerling and Migdal's
The Palestinian People: A History, the roots of Arab nationalism were already in place at the time of the POD, and the Arab revolt of 1834 helped to galvanize an embryonic national identity. Arab nationalism was of course in a very early phase during the nineteenth century, and the Arabs' grievances related more to perceived oppression and neglect by a distant capital than to any grudge against the Sultan as such, but it did exist.
It will, however, develop differently in TTL. For one thing, the competing nationalism will be a more inclusive
Ottoman nationalism rather than an exclusively Turkish one, so the Arabs will have some space to become Ottoman patriots. For another, as you say, the Ottomans are delivering the goods whatever their faults may be. The Arab nationalists' focus for the time being, albeit with exceptions, will be greater rights within the empire - and as I said to Daztur above, the Ottomans will eventually have to come to terms with the diversity of their subject population.
Islamic Central Asians might not be able to fall into the strategic niche stronghold US Jews were able to carve for themselves OTL, but I daresay if the Tsar winds up on the wrong side of the war from the point of view of American elites, they will be able to strengthen their hand in American ethnic politics considerably, especially if the US has good relations with any breakaway Central Asian states the Ottoman/British alliance will no doubt seek to foster.
The Central Asian Muslims may be able to take that strategic position simply because there are fewer Jews! The Jewish niche in the United States won't be as large (although it will still be significant) and another skilled, educated and literary-minded immigrant population - such as elite Kazan Tatars or Kazakhs - could fill some of the "Jewish" roles
alongside the contemporaneous Jewish immigrants. And yes, they could easily be a bridge between the United States and postwar Russia - and even if the US stays neutral, it could be neutral in one or the other side's favor.
Also, while (as you say) France will not be without credit among American Muslims, the Central Asian immigrants will for obvious reasons be much more focused on Russia. The Muslims most likely to favor France will be in South Carolina, which has increasing trade with French West Africa.
Update possibly tomorrow, more likely Thursday.
