Read the excerpt from the Gulf of Tonkin Resolution."...These attacks are part of a deliberate and systematic campaign of aggression that the Communist regime in North Vietnam has been waging against its neighbors and the nations joined with them in the collective defense of their freedom...”Gulf of Tonkin Resolution, 1964
Answer
A
Expansion of North Vietnam would not be prevented by armed defense.
B
There was more foreign support for North Vietnam than South Vietnam.
C
The inaction of South Vietnam’s allies was a threat to the country’s freedom.
D
Domino theory made politicians fear the spread of communism in South Vietnam.
Explanation
The excerpt describes North Vietnam’s actions as a deliberate campaign of aggression against neighboring countries. This reflects the fear that communism could spread through the region, a concern often associated with the domino theory. The choice about inaction is not supported: the excerpt emphasizes collective defense, not that allies were failing to act.
