That's interesting. These days I've been seeing more parallels with the First World War than the Second World War or after, even though Tolkien was writing the books during that time. It's probably that image of four country lads going off to distant lands to fight an enemy in dark lands and coming back changed, for better or worse (in Frodo's case, it makes me think of PTSD). But then it could be applied to many wars of this type.
Also, I never considered Sauron as being like Big Brother until now. The more you consider things, though...
