Was Leninism elaborated only on Russian soil, for Russia alone, and not on the soil of imperialism, and for the imperialist countries generally? Do such works of Lenin as "Imperialism, the Highest Stage of Capitalism," "The State and Revolution," "The Proletarian Revolution and the Renegade Kautsky," "Left-Wing Communism, an Infantile Disorder," etc., apply only to Russia, and not to all imperialist countries in general? Is not Leninism the generalisation of the experience of the revolutionary movement of all countries? Are not the fundamentals of the theory and tactics of Leninism suitable, are they not obligatory, for the proletarian parties of all countries? Was not Lenin right when he said that "Bolshevism can serve as a model of tactics for all"?
