Did the Vietnam War increase tensions between the superpowers?

Yes, the Vietnam War significantly increased tensions between the superpowers, particularly the United States and the Soviet Union. The U.S. intervention in Vietnam was driven by the desire to contain communism, which heightened Cold War hostilities and led to further military and ideological confrontations. Additionally, the war spurred the Soviet Union to provide more support to communist movements globally, exacerbating the rivalry and leading to a more polarized international landscape.
