Question: why did the united states get involved in wars in korea and vietnam?
Answer: The popular theory for why the U.S. fought wars in Asia (Korea and Vietnam) was to stop the spread of communism, the so called “Domino Effect”. ... Yes, the U.S. had to intervene to repel an attack from a communist country, but it was more of an attack on a peaceful, relatively prosperous country by an aggressive dictator.
