contributed to the political decision to become
involved in the Vietnam War.

The domino theory  is basically ,if one new country went communist in Asia then it would begin a chain reaction that would cause several more Southeast Asian countries becoming communist. it was the reason the united states went into the Vietnam war. since everyone was becoming a communist no laws were really set so they went into war.

Eventually the war weakened the American economy, divided the people, and eroded the nation's morale.
