Many early cold war novels had a strong focus on propaganda, either subtly or overtly. Some novels in the Western bloc would promote the values of democracy and capitalism as superior to communism, while in the Eastern bloc, novels might do the opposite. The settings of these novels were diverse, ranging from the urban landscapes of major cities involved in the Cold War like Berlin and Washington, to more remote areas that could potentially be battlefields or sites of secret operations. Characterization was also important, with characters being portrayed as either heroes defending their side's ideology or villains trying to undermine the other.
One characteristic is the exploration of the ideological divide. These novels often depicted the tensions between the capitalist and communist blocs. For example, some novels showed the paranoia and suspicion on both sides. Another aspect was the use of the Cold War backdrop to create a sense of global threat. Novels might feature the threat of nuclear war, which was a very real fear during that time. Also, characters in early Cold War novels were sometimes used to represent different political ideologies, and their interactions and conflicts reflected the broader geopolitical situation.
The early cold war novels were often marked by a sense of unease and uncertainty. The threat of a potential war was always looming, so the atmosphere in these novels was tense. They frequently dealt with themes like espionage. Spies became a common element as both sides were trying to gather intelligence on the other. The novels also sometimes showed the impact of the Cold War on ordinary people's lives. It wasn't just about political leaders or military strategists, but how the average citizen was affected by the geopolitical standoff.
