From the prelude we know about UIS 2011 UIS interventon in Georgia. However, I think it wasn't mentioned that Georgia is still UIS Republic or it was only border clash about Osetia or Abkhazia.
About other republics, it seems that UIS in 2012 is composed by Russia, Bellarus, Ukraine, Moldova, Serbian Kraina and Kazakhstan. All have Russian/Slavic majority.
We know Azerbaijan was kicked out by Lebed in 2004 and Armenia leave UIS in 2005.Also Russians retreats from Tajikistan after fall of Zhirinovsky.
The question is, what about rest of Central Asian republics, However we can see Lebed is willing to leave trublemaking non Russian, or non Slavic republics. So it is possible they will follow suit and being abadoned by Moscow after many years of costfull pacifications in name of turn UIS into country composed mostly by Slavs with solid Russian majority. However it wasnt yet mentioned.
BTW, we yet far from it, but I think that see this TL continuing after 2003 will be nice
