Korea was split into the two separate countries of North and South, Korea along the 38th parallel. Tensions between the two countries worsened when other countries began to get involved on both sides. The communist country of North Korea was supported by Russia, China and others. The democratic South was supported by the United Nations and the United States. In 1950 the United States got involved and over the next three years more than 1.5 million US service members would serve in Korea. During the three years of the war 133 Medals of Honor were presented. Although more than 150, 000 Jewish American men and women were serving in Korea at that time, not one received the Medal of Honor.
