The American economy thrives on the production of military equipment. Why not shove a stick up the Nth Koreans ar$e, and see if it results in a few fireworks?!... particularly when the U.S. economy is in the doldrums!
No point in having all this high tech weaponry if you can't show it off to those annoying upstarts from NK!
Besides, I believe there's some unfinished business from around 1953, that needs to be tidied up!
Seems like there's no time like the present to do it!
