I'm not talking about the ridiculous expense of it. I'm talking about WAR being such an old fashioned thing that it doesn't work in the modern world for "nation states". A "real" war would mean global nuclear destruction. What we have now is a "war on terror" that isn't even a "war" (but words do get abused when used for George Orwell 1984 type propaganda, and that's what we're getting). The terrorist thing is more of a "police action". The difference? The big main one is that a war is fought and won or lost, but a police action goes on without end, and acts a lot more low key. And a President can abuse his power when he's a "War President" but he can't if he just has an endless police action going on in the background.
We should have a strong National Guard for here, for when we get our big earthquakes. And to keep Canada from attacking (did you know they once, way back, had a plan to conquer Minneapolis? - and I bet they STILL want it - then it would be thought of here as a Southern Town - southern for them anyway).
And NATO can take care of international war stuff, if we really decide that we need to bomb the tarnation out of something. NASA can be in charge of developing the highest tech drone planes and robot spies (they'll use them on Mars, too).
But as long as we have the Pentagon then we'll have war drums LOUDLY drumming for all sorts of things. Like they say, when all you have is a big hammer, the world looks like a bunch of nails.
