Stephan:   Although this is too polemic, it nevertheless makes a case I have not seen elsewhere, and which I think is correct. Military technology is being guided by new geostrategy. There will be no more tanks rolling across Poland; there will be no coldwar multiple nuclear exchanges. Instead it is asymmetrical warfare, mostly in urban settings. Projecting power is no longer long range bombers, missiles and submarines. It is about drones that can kill individuals, and small gatherings no matter where they are, with long range precision, and arm's length safety. But this transition is going to cause massive disruption of the existing defense contractor infrastructure, just as sail makers were wiped out by steam.
