Wow. Political symbols almost 'helped' us lose the cold war? Putting a bit much into a symbol aren't you? BTW, it started as a symbol for nuclear disarmament in the 1950s (that is unless you believe the kookier sites about Nero's Cross and Celtic symbols for death). And we have a problem with nuclear disarmament why again? What about those treaties signed by great men like Nixon and Reagan?
It was used by protesters during the cold war who tried to tie our hands in defense. Had Reagan listened to them we would have lost the Cold War.
Try as you might it was political then and political now.
And we have a problem with nuclear disarmament why again?
Because North Korea has them and Iran wants them.
