War is something that acts as a catalyst for improvement both technilogically and socially. War spurs scientific ingenius by giving it a goal, and by allowing for and increased appropriation of funds. Very many of our modern day items came straight out of WWII alone. Radar, Penicillin, Teflon, synthetic rubber, jet engines, space capable rockets, the Computer, the wireliss phone, ect ect ad nauseum.
