Should the Russian Left rehabilitate the "greater" RSFSR idea?

[Die Neue Zeit]

Given the mess in the Ukraine, the mass Crimean move to join the Russian Federation, and Putin's alarming "Russkii" ethnic statement (http://www.washingtonpost.com/blogs/monkey-cage/wp/2014/03/19/vladimir-putin-ethnic-russian-nationalist/) and dubious blaming of both Western powers and "the Bolsheviks, for a number of reasons -- may God judge them -- [who] added large sections of the historical South of Russia to the Republic of Ukraine [...] with no consideration for the ethnic makeup of the population, and today these areas form the southeast of Ukraine," isn't it about time that the Russian Left respond to this speech and background history thinking outside the geopolitical box?

Much of the Russian Left's (from the Left Front to well-meaning leftist activists within the RCWP-RPC and within the CPRF cesspool) nostalgia for the Soviet Union is misplaced. Shouldn't it start thinking outside the geopolitical box by rehabilitating the "greater" RSFSR idea put forward in 1922 by the People's Commissar of Nationalities as the alternative to the Soviet Union?

The near abroad should be welcomed with open arms and affirmative action into a stronger geopolitical entity, but that entity for the Russian Left should be a new Rossiyskaya / Russian Socialist Federative Soviet Republic.

I don't really see why anyone on the Russian left would think that supporting pan-Russian ethnic nationalism could be anything other than reactionary in the context of Putin's attempt at expansionism. Really this approach wreaks of posing a hypothetical question for the sake of "creativity" rather than any actual merit in the idea

^^^ The Left Front held demonstrations recently supporting the Crimean move to join the Russian Federation (thankfully), so there is merit to this consideration.
