Final answer:
Pearl Harbor could have been prevented if the U.S. had been more actively supportive of other countries and if they had taken the intercepted warnings more seriously. The decision of whether or not to engage in retaliatory action depends on careful analysis of the situation and potential outcomes.
Step-by-step explanation:
Pearl Harbor could have potentially been prevented through several means. Firstly, if the United States had been more actively supportive of countries like Britain, France, and China, the Japanese military may have reconsidered their aggressive actions. Additionally, if the U.S. had taken the intercepted warnings of a potential attack more seriously and increased internal security measures at all Pacific bases, they may have been better prepared for a carrier-based attack from the Japanese navy.
As for the question of retaliation, it is a complex issue. There are arguments that can be made both for and against doing whatever is necessary as retaliation. Many factors need to be considered, such as the potential consequences of retaliation and the overall goals and values of the nation. Ultimately, the decision of whether or not to engage in retaliatory action would depend on careful analysis of the situation and the potential outcomes.
