On April 5, 1933, Franklin Roosevelt did it right here in the White House. On August 15, 1971 Richard Nixon came back from Camp David and did it. On September 22, 1985, Ronald Reagan went to the Plaza Hotel and did it.

American presidents are not the only ones who did it. Chinese communists do it often and are doing it now, as is Japan’s Prime Minister Shinzo Abe. And Mario Draghi, the head of the European Central Bank, finally decided to do it right there in Frankfurt even though his German overseers disapprove.
