Vietnam was a focal point of U.S. national security strategy during the Cold War, primarily due to the fear of the spread of communism in Southeast Asia, often referred to as the "Domino Theory." The U.S. became militarily involved in Vietnam to support the South Vietnamese government against the communist North, aiming to prevent a broader regional shift towards communism. This involvement escalated into a protracted conflict that significantly impacted U.S. military and foreign policy, ultimately leading to a reassessment of American intervention strategies worldwide. The Vietnam War also raised critical discussions about military engagement and its implications for national security.

Communism. If North Vietnam hadn't been a communist nation, the US would have stayed out of it. It would have been none of Uncle Sam's business. Nations around the world have always and will always have their own problems, and other than some "National Security" reasons which would usually involve "covert operations" on the part of the US (like Central and South America were heavily used for during the cold war days) the US stays out of them (officially).
