The real problem isn't the price of the missiles. I wouldn't even care about the price of the missiles if they actually worked. But Iran kicked our butts. We don't have air superiority, we cannot guarantee the shipping of oil through the straight of Hormuz, or anywhere else in that hemispheres, our bases and our aircraft carriers are useless.
I wanna know what they've been doing with our trillions of dollars, because it sure as heck wasn't making an effective military.
They ate the money. They got really fat and slow.
