Answer:
Gulf of Tonkin incident
Step-by-step explanation:
The Gulf of Tonkin incident was the event that led to the United States engaging more directly in the Vietnam War. The confrontation involved North Vietnam and the United States in the Gulf of Tonkin. Originally, the United States had reported two attacks, and blamed them on North Vietnam. However, over time, there was a widespread belief that at least one, if not two of the attacks were false. This could be repeated in the case of the example if not enough information is gathered before retaliating.
