This collection of essays Wells wrote during the first two years of the war is fine but never terrific. It's more of a curiosity than a compelling piece of writing. The chapters on aerial photography and tanks are pretty good; others are replete with allusions to figures of the time that I couldn't catch. Wells argues that the only way in which wars will be eliminated is for all of the world's ten thousand religions to merge into one grand one, since people fight for God more enthusiastically than for their countries. Not much to recommend here. ( )
