I have mixed feelings about Teller. 

Whatever you may think of him, you must accept that he believed
_passionately_ in the concept of Mutually Assured Destruction as a
technique to keep the superpowers in check. And, given that none of
his bombs were ever actually used, it would seem that his policies
worked.

He had strong feelings about the social implications of his work, and
discussed them frequently with his fellow scientists. A famous SF
author (Gregory Benford, I think) worked with Teller, and reported
that Teller would read SF stories to stay in touch with social
thinking about nuclear weapons.

I don't really agree with Teller's decisions; if I were in his
position, I think I would have wiped my hands of nuclear weapons and
walked away. But I respect the sincerity of his morals, at least, and
I can't argue with the results.
