I met Dr. Teller at Clemson University in the 1980's while working on my BA. He was part of a panel debate with Charlton Heston defending Reagan's decision to place a new class of midrange nu-cu-lar missiles in West Germany. A surreal debate to be sure. He seemed very animated when discussing the possibility of a global holocaust. Almost Dr. Strangelove-ish.
I remember how he always came back to the same point though, " ... don't worry, we have weapons you can't even imagine ... if we need them, they will be there ..."
