Answer

Brief Explanations:

Arms - race refers to competition in building up military arms, brinkmanship is a strategy of pushing a dangerous situation to the brink of disaster to gain an advantage, and containment theory aimed to stop the spread of communism by various means but not with the specific "fall - like - dominoes" concept.
