The political line dictated by Lenin can in fact be summarized by the following formula: strategy to the class movement; tactics, and only tactics, to the institution, or rather, to the party, to representation and the vanguard. The independence of the proletariat constitutes strategic hegemony, where insurrectional power and the revolutionary project are formed. This is the reality on which the vanguard must focus its attention if it wants to establish a tactical proposal. The radical transformation of revolutionary tactics, dictated by Lenin beginning in April 1917, is not, therefore, some artist’s gesture, but the political recognition of hegemonic maturity, of the strategic capacity of the proletarian masses (the peasants, workers, and soldiers organized into soviets) to seize power.
