Answer:
A major similarity between the Korean War and the Vietnam War is that both wars started as civil wars that faced American-led democracy against Soviet-led communism.
Explanation:
-The Korean War took place between 1950 and 1953. Its components were the Republic of Korea (or South Korea), supported by the armed forces of several countries commanded by the United States; and the Democratic People's Republic of Korea (or North Korea), supported by the People's Republic of China and the Soviet Union. The war was one of the earliest episodes of the Cold War. Killing more than 3 million civilians and almost 15% of the population of the North, it constitutes one of the bloodiest wars in history.
-The Vietnam War was fought between 1955 and 1975 to prevent the reunification of Vietnam under a communist government. In this war the Republic of Vietnam (South Vietnam), with the support of the United States and other allied nations, faced the local guerrillas of the National Front for the Liberation of Vietnam (Viet Cong) and the Army of the Democratic Republic of Vietnam (North Vietnam), backed by China and the Soviet Union. It is estimated that between 3.8 and 5.7 million people died in total. 58,159 American soldiers died and more than 1,700 disappeared.
