Marxists are certainly critical of Putin and the Russian Federation, and see it as an incredible fall from their proud and progressive soviet past. However, the biggest obstacle to socialism globally is the US Empire, and Russia is presently playing a progressive international role in undermining it, and being a valuable trading partner for countries like China, Venezuela, the DPRK, etc. Further, the biggest opposition faction to the nationalists are the communists, not the liberals, so in time it is likely they will return to socialism.
