Obviously, any technological advancements that would have happened between the 60's and now would probably not have occurred, but I was wondering what the other possible consequences could be.
Further details: There was an all out nuclear exchange between the USA (and her allies) and the Soviet Union in the Autumn of 1962. I'm going to assume South America, Africa, India, and Oceania were spared from direct targeting (perhaps China too). There was no warning.
