These are the connections I can see (HINT: I am not a historian):
- Washington won the Revolutionary War - Truman ended WWII with the Bomb
- Washington oversaw the birth and building of the United States of America - Truman oversaw the rebuilding of Western Europ with the Marshall Plan.
- Washington was awesome - Got nuthin' for Truman
"Give 'em Hell Harry!"
Perhaps my memory is longer than yours.
