We just live in one of all the possible timelines, were we just didn't anihilate ourselves yet. Seriously, we were so fucking "lucky" several times now in regard to the nuclear holocaust, that the many worlds theory becomes more likely every day

It would be still up to the higher ups to make the call to start a total nuclear war, which they were rather unwilling to do
