Final answer:
The question lacks specifics about the event in 1971 that required a response from the United States to Britain's actions; hence, it is not possible to provide a detailed and accurate answer without further information.
Step-by-step explanation:
The question seems to pertain to a historical event relating to the actions taken by the United States in response to Britain's actions. However, the provided information does not specifically mention an event from 1971 that necessitated a response from the United States to Britain, and without further clarification, it is challenging to provide an accurate answer. Generally, historical actions by the United States in response to British actions span a range of events, from the War of 1812, diplomatic engagements post-World War II to adjust foreign policy from isolation to engagement, to the condemnation of the United States' actions by the United Nations regarding the Invasion of Grenada in 1983 and other international matters. Without a clear reference to a specific event in 1971, it is impractical to furnish a detailed and factually accurate answer.
