Brian Becker, a national leader of the Party for Socialism and Liberation, discusses the Sino-Soviet split that began in the 1960s with its underpinnings in differing approaches on survival against U.S. imperialist threats. The pressures of imperialism resulted in a split – first ideologically and later state-to-state – between these socialist nations. This history is important for progressives and revolutionaries to understand today as the U.S. continues its threats against Russia and its maneuvers to destabilize and overthrow the Communist Party-led government of China.
