9. Vietnam War
The Vietnam War is one of the most controversial wars that the United States has been involved in. The U.S. entered the war with the intention of preventing communism from spreading from North Vietnam into South Vietnam. However, looking back, we can see that a lot of decisions made during this war were poorly made. President Kennedy was against the war, however, after his assassination President Johnson pushed for it and one of the biggest motivators was more oil for the U.S. Many protests were held as no one knew why we were involved in the war in the first place and no one wanted to continue the invasion.
