The term “Cold War” is used to describe the period of geopolitical tension between the United States and the Soviet Union and their respective allies after World War II. The Cold War was unique in that it did not involve direct military confrontation between the U.S.-led Western bloc and the Soviet-led Eastern bloc, giving this politically strained period its name. Instead, it was a war of ideologies, primarily between capitalism and communism, and a struggle for political influence and economic power. The term was first used by English author George Orwell in a 1945 article to refer to a nuclear stalemate between what he called “super-states.”

The presence of nuclear weapons played a significant role in keeping the Cold War “cold.” Both the United States and the Soviet Union possessed massive arsenals of nuclear weapons, which acted as a deterrent against direct military conflict. The fear of mutual destruction kept both sides from engaging in a full-scale war, leading to a tense but relatively stable standoff.

The Cold War was also marked by a fierce ideological rivalry between capitalism, championed by the United States, and communism, led by the Soviet Union. This ideological battle was fought through propaganda, espionage, and the support of allied nations around the world. The competition for global influence was intense, but it remained largely within the realms of politics and ideology rather than open warfare.
