<span>C. the American army</span>
Answer: I would characterize the U.S. involvement in Vietnam as a failure of American foreign policy.
Explanation: The US caused a lot of their own troops to die and left several behind. They also gassed Vietnam which caused a lot of environmental damage, birth defects, deaths,cancers, and deaths. On the whole, the US failed their citizens and caused a lot of innocent people to be killed thus characterizing this as a failure of foreign policy.
Hope this helps! :)
