What two forms of government began to experience mutual tension and hostility following ww2?

Following World War II, the two forms of government that began to experience mutual tension and hostility were capitalism, primarily represented by the United States and its Western allies, and communism, led by the Soviet Union. The ideological clash between capitalism and communism fueled the Cold War, marked by political rivalry, military build-up, and proxy wars. This tension was further exacerbated by events such as the Berlin Blockade and the Korean War, solidifying the divide between the Western bloc and the Eastern bloc. The conflict shaped global politics for decades, leading to a bipolar world order.
