"But it would have been interesting (more interesting?) if Mordor had been given the kind of seductive glamour that the Third Reich had."

but... doesn't it, in some ways? LOTR can be sort of read as an allegory about WWII. saruman is certainly seduced by the power of mordor. maybe the "seductive glamor" would have been a little more evident if the army had been a human army and not an orc army-- although there were humans fighting on mordor's side- the pirates and the people from the south...

or perhaps, the ring portrays evil is more the way you're talking about. it tempts pretty much everyone with thoughts of the good they could do by wielding it- i'm thinking of boromir, galadriel, and gandalf, in particular- but it's really the ultimate artifact of sauron's evil.

just thinking out loud.

also, did you know that stalin tried to assassinate john wayne? i may have posted about this before.
