Agree with you. Sadly we don't even need to read 1984 anymore. War is the engine of capitalism. US IS the capitalism..hence this nation is at war at every generation.
I didn't grow up here, I'm, Italian, what I find truly amazing, is the apparently unlimited resource of youth WILLING to enroll in the Army and go to war. You realize that happens only here in US in the Western world? No other kid anywhere would do it...but here kids run to the Marines camps...why?
You can see why the country usually does well when it's not in a war. I'm sure most people who post in this forum have read it, but 1984 by George Orwell has some interesting insights on the ulterior economic purposes of wars.
