The cold war ended happily for the US while Reagan was President.
the president of he us after the war was James Madison
So far there have been two world wars.The US President when the first one started was Woodrow Wilson; the US President when it ended was ... Woodrow Wilson.The US President when the second one started was Franklin Roosevelt. The US President when it ended was ... Harry Truman, but that's because he was Roosevelt's Vice-President and Roosevelt died shortly before the war was over.So a President can clearly remain in power "if a world war breaks out," though remaining in power if his own personal death "breaks out" is a considerably more difficult proposition.
James Madison was still president when the war ended. James Monroe succeeded him in 1817.
The U.S. entered the war on April 6th, 1917. The U.S. president Woodrow Wilson created the Treaty of Versailles which ended the war.
