Why was the Vietnam War often portrayed as a war of reunification?
assistant
The Vietnam War was often portrayed as a war of reunification because the United States government used the "domino theory" to justify the American intervention in order to prevent regional domination by China, overlooking centuries of hostility between the Vietnamese and the Chinese. Throughout the war PAVN/VC troops were continuously portrayed as "brutal, cruel, fanatic, sinister, untrustworthy, and warlike".
