The Constitutional power as "Commander in Chief" has evolved into the very important modern role of "crisis manager." In the 20th century, as the United States gained world leadership powers, the President has become a key player in international crises. In the case of war (such as the Korean War, the Vietnam War, and the Persian Gulf War) or less famous regional conflicts (such as those in Kosovo, Somalia, or Haiti) the President must go into "emergency mode" and concentrate on the immediate problem. Domestically, crises may occur — such as urban riots, hurricanes, or forest fires — that require the President to schedule time to coordinate government responses to the situation.
More than anyone else, the President symbolizes the country — its people and its beliefs. In this role, a President performs many ceremonial duties, such as receiving foreign dignitaries, throwing the first baseball of the season, and waving to crowds. These actions are not trivial. Strong Presidents must exude confidence, not just in themselves, but in the American people as well. The best ones have had an intangible charisma that creates public confidence.
