Origin of the term Socialists have long held sharply divergent views on major international crises. For example, the
internationalist–defencist schism during World War I led to the split of the anti-war
Independent Social Democratic Party of Germany (USPD) from the pro-war
Social Democratic Party of Germany (SPD) and the split of the pro-war
Social Democratic League of America (SDLA) from the anti-war
Socialist Party of America (SPA). These divisions were also present in the 1930s, after
Leon Trotsky was expelled from the
Soviet Union by
Joseph Stalin. All
Trotskyists opposed
Stalinism, but differed on why and how. Trotsky argued that the Soviet Union was a
degenerated workers' state. Although a small ruling class had taken control, the Soviet Union had made (
social revolutionary) gains for workers and should be defended from outside aggression. Instead of outside invasion, the Soviet
working class should lead a
political revolution to seize back control. From 1929 to 1933 (the
Third Period), the Soviet Union attacked unaligned socialists and social democrats as
social fascists. In a sharp reversal after
Adolf Hitler's rise to power, the Soviet Union pursued a
popular front strategy from 1934 to 1939 and again from 1941 to 1945, in which communists attempted to build broad anti-fascist alliances. In this view, the world was divided into
fascist and
anti-fascist camps: In contrast, other Trotskyists (such as
Sam Marcy of the
Workers World Party After World War II During
decolonization, billions of people won freedom from imperialism in Africa and Asia. Most of these countries did not pick a "side" in the Cold War. These divisions led to
Alfred Sauvy's
three-world model in 1952: • First world: Capitalist countries, led by the United States • Second world: Communist countries, led by the Soviet Union • Third world: All other countries Both the United States and Soviet Union supported the identification of the first camp with capitalism and second camp with communism, in order to orient their allies away from infighting and toward fighting the "other" camp. NAM represented an alternative to the two-camp order of the Cold War. The NAM is sometimes associated with
Third-worldism, which promoted
Global South governments (as representatives of peasants and workers and
people of color) against
Global North governments (as representatives of capitalist imperialism). Third Worldism identifies imperialism as the "primary contradiction" in the world, and some Third Worldists sort the world into two camps: Imperialist countries and imperialized countries. and again after the
Russian invasion of Ukraine in 2014. In the modern self proclaimed "anti-imperialist" second-campist view, there are two real camps: • First camp: "Imperialist" countries, led by the United States; similar to
imperial core, to Global North, or to
Western world • Second camp: "Anti-imperialist" countries, possibly led by China, Venezuela, or Russia; similar to the Global South, or
peripheral countries, or to
non-West but often simply defined as any nation that stands in opposition to the first camp. • Third (non-)camp: Unaligned countries == Criticism ==
