its true weapons are unproductive capital goods, and money could be better spent, but your point about 3th world counties buying high priced weapon systems is only half thru, even brazil makes fighter jets and angola has a triving small arms industry, 3th world countrys have taken on western developement models in more ways than one. The logic of long production runs is inescapable, even for counties at peace. America is a grotesque example of a counties economy deformed by the arms trade but it is something that has taken place in nearly all western economies to a greater or lesser degree, even German.
