The Vietnam War had significant cultural, social and political impacts. Millions of life were lost, and thousands went missing during the 20-year conflict. Vietnam also became a communist nation as the result of the war.
The United States got involved in the Vietnam conflict to keep communism from spreading throughout Southeast Asia. At first the United States only aided France with military aid and advisors, but after the French suffered a major defeat at Dien Bien Phu in the north-western hills, the French pulled out and the United States took over the burden of the war.
