Putin has to find broad popular support — rely upon the communists, the winners of the parliamentary elections, and remove the most hated and most corrupt officials he inherited from Yeltsin's administration. This would entail parting ways with neoliberalism's model and embracing nationalization of resources, mobilization economics, putting an end to the offshore activities, repatriation of funds from overseas banks, progressive taxation (if not confiscation) of the super-rich and their assets.
However, the most interesting part of the story remained obscured for Western readers, and that is the comeback of communists. In the 1990s, the story of the decade was the demise of communism. It was supposed to be dead for good, this aberration of sacred property rights; and celebrating its death, Francis Fukuyama declared The End of History. But apparently rumours of its death were somewhat exaggerated.
It has taken longer than I thought it would, but I remember well (after the Berlin Wall came down and George W. Bush was sitting on his hands rather than jumping in with the huge aid he should have) thinking about and saying how first the nations will all be nationalistic and capitalistic and then regain their senses backing away from the greed and selfishness (because they never work) not to Stalinism but democratic socialism.
