If you could honestly truly imagine how much space we have up there that is left wide open for anyone to try and use, you would get the need for the jets... And let me tell you, the risk is higher than you would like to assume.
I keep hearing more and more about the north. Not in the news, but from people that might know a thing or two. I've done more winter work this year than ever, and there's a reason for it.
Now, I'm not happy about the government not being clear about ANYTHING they do. I think way too many things get passed before the public is aware of them or even has a chance to voice an opinion.
But, our security is important, and the north is more valuable than you know. It's pretty much entirely open for anyone to come over the top of the world. Russia (yeah, I know you think there is a fat chance) or China could easily take that route. If WE don't take the responsibility for our own nation, then the Americans will gladly step up, and then I think we would be in a really bad spot...
