Why Trotsky believed the socialist revolution could never stop at a single nation's borders.

In short: Trotskyism is defined by the theory of permanent revolution, which argues that in economically backward nations, the capitalist class is too weak to lead a democratic transformation. Instead, the working class must seize power and immediately push for global socialist revolution to survive against hostile international pressures.

At the heart of Trotskyism lies the theory of permanent revolution, formulated by Leon Trotsky in 1905. Unlike classical Marxists who believed that feudal societies must first undergo a bourgeois-democratic revolution to develop capitalism, Trotsky argued that in countries like early 20th-century Russia, the capitalist class was too subservient to foreign interests and fearful of the proletariat to lead such a change. He contended that the working class, though a minority, was the only force capable of overthrowing feudalism and establishing a workers' state.

However, Trotsky recognized that a socialist state in a backward, isolated country could not survive indefinitely against the pressures of a hostile capitalist world. His solution was to make the revolution 'permanent,' moving uninterruptedly from the bourgeois stage to the workers' revolution, and then outward to advanced capitalist countries. This internationalist outlook was rooted in the belief that socialism could only be fully realized when the global working class conquered state power, thereby ending international competition between laborers.

This ideology placed Trotsky in direct opposition to Joseph Stalin, particularly regarding the Soviet Union's trajectory. While Stalin promoted 'socialism in one country,' Trotsky criticized the growing Soviet bureaucracy and the suppression of democratic participation. He characterized the USSR under Stalin as a 'degenerated workers' state' because it lacked the workers' self-management and democratic control he deemed essential. By 1927, these ideological clashes led to Trotsky's expulsion from the Communist Party and his eventual assassination in Mexico City in 1940.

Today, Trotskyism remains distinct for its emphasis on transitional programs, the united front tactic against far-right parties, and the necessity of socialist democracy. While orthodox Trotskyists continue to argue that city-based working-class struggle is central to revolutionary success, the movement maintains a critical stance toward any state that claims to be socialist while lacking the democratic foundations of a true workers' state.
