The challenge of the Left Opposition, 1926-27

The second of three volumes documenting the struggle in the Soviet Union in the 1920s led by Leon Trotsky to defend V.I. Lenin's proletarian internationalist course against the counterrevolutionary policies of Joseph Stalin and the privileged caste he spoke for. This volume covers the period of the United Opposition bloc of Trotsky with Gregory Zinoviev and Lev Kamenev. It takes up the debate over "socialism in one country" vs. organizing to extend the world revolution; the battle to maintain the worker-peasant alliance; the threat of a new war against the Soviet Union by the imperialist powers; the growing use of slander, falsification, and violence by Stalin's backers to intimidate and silence the working class vanguard; and much more.
