I believe that Russians have been relying on external aid to delay putting their house in order. Foreign aid should not give Russia an excuse for postponing political, economic and legal reforms. The best policy is hands off. This forces the Russians to acknowledge that the crisis they face is of their own making. They must solve their own political and economic problems.
Further aid is counterproductive.
In light of the current crisis, this seems least likely. A restoration of communism. This too seems unlikely for it would involve a vast amount of private property being confiscated and the confiscation of much new wealth created since 1989. A statist economy where the state is the supreme power regulating and heavily controlling the degree of private business that already exists. Wages and prices heavily regulated by the state.
