Question

read the excerpt and answer the question that follows. china is so large, looms so high just beyond the frontiers, that if south viet - nam went, it would not only give them an improved geographic position for a guerrilla assault on malaya, but would also give the impression that the wave of the future in southeast asia was china and the communists. -president john f. kennedy, televised interview, september 9, 1963 which idea reflected in these remarks formed the basis for u.s. involvement in vietnam? (8d) nuclear deterrence domino theory iron curtain flexible response

Explanation:

The Domino Theory suggested that if one country in a region fell to communism, neighboring countries would follow like a row of dominoes. Kennedy's remarks imply that if South Vietnam fell (to communism), it would lead to further communist influence in Southeast Asia, matching the Domino Theory. Nuclear deterrence is about nuclear weapons, Iron Curtain was about Soviet - Eastern Europe division, and Flexible Response was about military strategy options—none fit as well.

Answer:

B. Domino Theory
