Final answer:
The 'leader of the three' likely refers to the predominant figure among the Big Three leaders of the major Allied nations during World War II. Leadership is subjective but can be attributed to moral law or a leader's ability and goals. Historical interpretations such as the Great Man theory highlight the significance of individual leaders in shaping events.
Step-by-step explanation:
The question posed appears to reference a historical context in which leadership is central to the discussion. In identifying the "leader of the three," looking at the passage regarding the Big Three is crucial. The Big Three refers to the leaders of the three major Allied nations during World War II: Winston Churchill of the United Kingdom, Franklin Roosevelt of the United States, and Joseph Stalin of the Soviet Union. Historically, the term "leader" in this context might be subjective, as all three were pivotal.
However, in many Western accounts, Franklin Roosevelt or Winston Churchill is often perceived as the leader due to their countries' resources and roles in the formation of post-war strategy. Specifically, for the Yalta Conference, these three leaders met to decide the postwar reorganization of Europe and Asia. In such historical analyses, leadership is often associated with the moral stance or ability of the figure holding power, as well as with their goals and actions.
Leadership analysis can involve understanding the nature of government and how leaders come to power, an inquiry that ties into government forms and interpretation. Questions about the qualities of a good leader, forms of government, and evaluation of leadership within different systems, such as communist dictatorships like that of Joseph Stalin, are all relevant to the study of history, particularly when focusing on individual leadership in shaping historical events.
Such discussions of leadership and governmental forms point toward a historiographical interpretation known as the Great Man theory, which posits that history can be understood primarily through the impact of great men, or exceptional leaders, whose actions and decisions have changed the course of history.
