The one that best describes the effect of the Vietnam War on the US economy is the first one and the third. The billions that the United States spent eventually caused a recession and the billions that the United States spent devastated the US economy until the early 1970s.
I believe the answer is: The billions that the United States spent eventually caused a recession.
The initial plan was to win the war and utilize the resources from vietnam along with several trade agreements to repay the expense that we made during the war. Since we lost and forced to retreat, the billions caused recessions that lead to more than 10% unemployment rate.
