Edward Teller died Tuesday at the age of 95. IMO, Dr. Teller was wrong to participate in the process that led to Robert Oppenheimer losing his security clearance–as unfortunate as his personal connections with active Communists were, I’ve never seen any convincing evidence that Oppenheimer was anything but a patriotic American. However, Teller was clearly right to support the development of the H-Bomb in the face of Oppenheimer’s opposition–had Oppenheimer’s position prevailed, the Soviet Union–still led by Josef Stalin at the time–would have been the sole nation on Earth with the most destructive weapon ever created by the human race. For that alone, I would suggest that everyone reading these words who is glad that we did not spend the last half century living in such a world (with all of the ominous and horrifying implications of that scenario), take a moment to remember Dr. Teller. Whatever his failings elsewhere, he was right when it really, really counted, and had the courage of his convictions in the face of formidable opposition.
