Answer: "Influence bargaining" refers to a negotiation or bargaining process where the parties involved seek to exert their influence over the outcome in order to achieve their desired result. This type of bargaining often involves leveraging one's power, resources, or position to sway the outcome in one's favor. In influence bargaining, the parties may use various tactics such as making threats, offering incentives, or appealing to emotions, in order to achieve their goals. The goal of influence bargaining is to have a significant impact on the decision-making process and to ultimately secure a favorable outcome for one's own interests.
Explanation: In the context of the text you provided, "influence bargaining" refers to the attempt by one party, in this case Japan, to use its position or actions to influence the bargaining process in order to achieve its desired outcome. The text states that the Japanese response to the April diplomatic initiative indicated an interest in discussions, but their terms were so severe that no agreement was in sight. The President of the United States was considering moving the fleet and was weighing the potential consequences of this action. The text suggests that if the United States were to move too many battleships, it would weaken the deterrent effect it had on Japan, and potentially encourage Japan's bargaining position. In this context, "influence bargaining" refers to the attempt by Japan to use its position or actions to shape the bargaining process in a way that favors its own interests.
