it's not a "problem" and i think that largely is the point though....like creating demand....one sells say f-16s to every country and then you get to justify the money for f-22s. my only thing is it's got to top out at some point.... (unless someone was trying to militarize space or something). you can't use f22s in say afghanistan because if one gets shot down or crashes it's like you lose...as one could almost buy afghanistan for the price of 1 or 2 f 22s.
i'm thinking the pentagon could cut out the middleman and dump every thing into computer battle simulators and get somekind of global simulator treaty where wars are fought on a huge computer....that way you only have to come up with new designs for weaponry instaed of actually building them.
