Someone should compare what the defence budgets and military research of the big spenders are spent on, with what the big items can achieve against the biggest dangers to world peace today, including in major areas of armed conflict.
Pirates, terrorists, insurgents, religious and political fanatics, social disruption, sabotage - what are the military means to counter these - and what alternative routes are there?

The revelations of what is going on in military research and the gung-ho exhibitions at arms fairs seem out of kilter with dealing with these dangers.
