Self production is a good thing in my opinion for a few reasons.
One, if you self-produce you are not subject to terms and conditions of the government of the supplier. No one can dictate to you your internal affairs, foreign policy, use of weapons etc.
Two, if you self produce you alone are the sole repositor of that weapons true capabilities and design features. Whereas a foe might be using a mass produced weapon sold by Rumsfeld Inc. and everyone knows whats its stregnths and weaknesses are. If you have a wild card it can make all the difference in a battle.
Three, competition is good. It drives mfg's in the US to strive to improve their death machines and lower prices in order to compete hence a further hollowing out of the American industrial base. Nothing personal guys.
