Answer:
showed the limitations of American power, leading to improved Soviet-American relations.
Step-by-step explanation:
The Vietnam War took place in 1959 and lasted until 1975. This war began as a conflict between two political strands that wanted to dominate the country, in a unified way. This political disagreement was strengthened by the cold war and the rivalry between the US and the USSR, which in an attempt to attack each other indirectly supported different Vietnamese political strands. The US had a lot of trouble in successfully establishing itself in this war, and ended up showing that although it was a military power, it had limitations. These limitations promoted a retreat from US attacks during the Cold War and prompted the government to seek slightly better relations with the USSR.
