A survey of the status as to preparedness in England, France, Germany, Italy and Russia. Appalling, in its assumption that such tremendous and seething activity can have but one outcome -- war. Pictures Germany as taking the old line of preparation, and counting on massed strength, and in contrast pictures the value of greater mechanization and greater mobility and fluidity elsewhere. France he shows as slow in preparations and in changing to the modern science of war, but now making up for lost time. England he recognizes as better prepared for home defense and policing the empire than for aggression. He indicates that past lessons are hard to learn and many old mistakes are made again. Section on Russia most interesting. Developments in air preparedness the most revealing. He questions the assumption that the next war will end civilization, and points out that man can take refuge from gas attacks in his own home. Too lenient in his assumption that humanity will have a chance, in view of the Spanish Civil War atrocities which he ignores. A book which should be read -- with an eye to how war can be avoided in the face of a general stampede.
