I hope it never ends.
The richest country in the world, even if it wasn't the USA, is always going to have the largest/most advanced military.
I think the article is complete BS. They keep asking this question:
The question the rest of the world is asking itself is: Who is the enemy America is arming itself so against? And why?
...
But against all this even the manufacturers of America's arms - like the aviation giant Lockheed-Martin - have been struggling for a decade or so to define the threat its top-shelf jets will be battling in the skies
It's not that we're preparing to fight any one country, or that these defense spendings are directly related to terrorism...we will perpetually be spending money on research and development to enhance our military. That's how we stay ahead of the game, in the case of any future threats.
