The threat that emerged as a popular subject of American invasion literature after World War II was D. Soviet occupation. This choice reflects the geopolitical climate of the time, particularly the Cold War era, during which tensions between the United States and the Soviet Union peaked.

Invasion literature often served as a metaphor for societal fears, and the looming threat of communist expansion fueled a plethora of novels and films that depicted Soviet forces invading and occupying the United States. Works from the 1950s through the 1980s often explored themes of espionage, subversion, and the struggle against totalitarianism, mirroring the anxieties of the American public regarding national security and the ideological battle against communism.

Therefore, the popular narrative of Soviet occupation in invasion literature can be seen as a reflection of historical events and sentiments, making it a resonant theme in post-World War II American culture and fiction.
