Potential Conflicts Following WWIII in 1962?

I would expect influence from North Africa (Algeria and Libya) and India in UK. The Americans might actually occupy everything from France to Norway and annex it as territory.

Most of the territory from France to Norway will be too radioactive or poisoned by chemical and biological weapons to be worth occupying.
Not to mention that even if those regions aren't much toxic and said elements have gone away, I don't see any reason the USA would go and annex parts of mainland Europe after a 60's WWIII.
