Truman actually gave the command to detonate the first nuclear weapon & he was the US president in office when man left the old world (conventional) and crossed into the atomic age in 1945. When that A-Bomb went off, the cold war began...even though the Soviets didn't get their bomb until 1949 (stolen from the US via spies).
