The US did NOT allow the communists (USSR) to expand during the cold war.
That's like asking why the Communists took over so many countries during the cold war. It's because they had the troops to do so.
The communists primarily fought against various capitalist and imperialist forces, particularly during the Russian Civil War (1917-1922), where they battled the White Army and other anti-Bolshevik factions. They also opposed fascist regimes during the Spanish Civil War and World War II. In the Cold War, communists faced off against Western capitalist countries, notably the United States and its allies. Additionally, they engaged in conflicts with nationalist movements and other political groups within their own countries.
Many countries were led by dictators in the Cold War .
