Just a few years ago I might have said yes to NORAD's growing obsolesence but that would've been a foolish thing to do. With Russia planting a flag under the water of the north pole, the USA sending a ship through the northwest passage and the increasing need the world has on oil I'd say that NORAD is far from useless. However, I do suspect that when a more sober, secular and definately smarter administration gets in office down here that we'll probably stop hearing about the USA's claims on the northwest passage.
Now as it stands we have just as much to worry about a beligerent President Bush's territorial claims and a beligerent President Putin's territorial claims. By utilizing these two giants against each other, by signing agreements with the other Polar countries in Europe we can reduce our risks all over the board, pit our two largest headaches against each other in a new cold war and more effectively manage our defences in the region.
We stand more to gain by sharing our resources in the North ( for a reasonable profit of course

) and I think we'll accomplish that with the next administration not the current one. This one is more concerned with the second coming of Christ, not the common sense sharing of energy and defence resourses against Russia. So those of you who think we ONLY have to worry about the Russians had better start googling the statements being made by this CURRENT administration pertaining to Arctic territorial claims.
Just my very humble civilian opinion.
