Eldridge Cleaver was an African American who was very outspoken about the impact the Vietnam War had on African Americans. He detailed the possible effects in a piece called "The Black Man's Stake in Vietnam".
Cleaver believed the Johnson Administration was facing a 2 front war: one in Vietnam and the other against the Negro revolution in the United States. He believed the two were linked in several ways, mainly from the relationship that connected the treatment of human beings in Vietnam and the treatment of blacks in America. The biggest threat to the U.S. at this time was undeniably the liberation movements around the world. Cleaver believed for the U.S. to achieve success in putting these movements down, it must be united and stable at home, which it was not because African Americans in America were aware their situation and their struggles.
Cleaver also believed that if the United States were able to form an alliance with the Soviet Union and they are then able to "unleash their anxious fury and armed might against the rising non-white giant of China", then the white population in the United States will then turn its aggression to the blacks once again. Cleaver wants some type of guarentee that the reign of terror against African Americans in America is not just being temporarily suspended (like it was for a short period of time after the Civil War but ended after Reconstruction), but banished completely.
In terms of the Vietnam War, Cleaver believes that the black man's interest lies in seeing a free and independent Vietnam, able to live on its own. He brings up past history relating to Vietnam, by saying when Africa, Asia, and Latin America were under colonial rule, blacks had no rights or voice and were supremely oppressed. However, once those nations began their attempts at freedom and independence, African Americans seized their chance at it as well and voiced their opinions. Therefore, Cleaver and his supporters urge all blacks in America to unite under one cause and one voice and lay everything they have on the line.
