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! :)
There is no picture to see to answer the question.
World War I killed more people (9 million combatants and 5 million civilians) and cost more money ($186 billion in direct costs and another $151 billion in indirect costs) than any previous war in history
I hope that this helps you
