Are they 100% immortal? If yes, then they are above Sauron. If no, then the USA can deal w/them. And let's say that middle earth takes the place of europe (they have a similar structure). How do they beat the USA then? Or even if they are right next to each other, how do they beat tanks?
OK, what about this:
The USA is on the edge of the middle earth world, and both sides are trying to get at eachother. They are about the length of half of the atlantic away. Who wins? (if this senario is too spitish for you, then Middle earth takes the place of South America and in between the two is unpopulated (no Mexico or anything, I mean it's there, but not populated in this senario)
