Unfortunately, it seems that building new "weaponry" is just about the Only major American industry that hasn't been outsourced to China and Mexico....yet. The Pentagon has spent billions on the F22 project, and I don't think that aircraft has been used in one mission, yet. Our forces left huge numbers of military vehicles behind in Iraq....for use by the Iraqi forces, and it seems that the Iraqi's quickly abandoned them the first time they engaged ISIS...so ISIS probably has plenty of US equipment.
