As far as I understand, Charles de Gaulle had as his Cold War policy the maintenance of France a significant power, even to the extent of forming some sort of non-American, Western European third party, although militarily aligned to NATO. He also wanted to maintain the colonial empire, build own nuclear arsenals and so on. Some of it may have been more to show off ("grandeur") than anything, but regardless.
Could something like this have happened in Britain during the same period? I imagine with Churchill being re-elected in 1945 (if that was the year he was replaced OTL) he might pursue a similar policy. What would the effects be on the Cold War? Would he fight to maintain power in the colonies, India in particular? How would Britain relate to America?
