Since the president is the commander in chief, he remains in office to lead the country. Many presidents have been in office during a war, and if such a thing happened during Barack Obama's term, he too would do what presidents have always done during war-time.
During World War Two, the US had two presidents. When the war began Franklin D. Roosevelt was the president. He died in office in April of 1945, and the Vice President, Harry Truman became the second US president during this war.
Eisenhower, John F. Kennedy, Johnson, Nixon, Ford. This surprised me!
The two presidents during the Vietnam War were JFK, and LBJ.
The president during World War I (1914-1918) was Thomas Woodrow Wilson. The presidents during World War II (1939-1945) were Franklin Delano Roosevelt and Harry S. Truman. Franklin Roosevelt died in office so there were 2 presidents.
Franklin Delano Roosevelt and Harry Truman, in that order.
