The two World Wars, with the intervening crises, are recognized as part of a single conflict, still going on-today's Thirty Years War. This is an allover picture, a useful single volume history while history is still in the making. End paper maps of Europe and Asia (1920-27) are supplemented by small scale maps, introduced as part of the text. The stress is on international relations, rather than domestic relations -- unless part of a larger whole. I was impressed with the objectivity and critical content and handling -- and occasionally some of the interpretations seemed controversial, but on the whole, the book is singularly detached and unemotional, presenting merely statement of chronological incident and fact. Approximately 900 pages naturally do not allow for very detailed elaboration either of events or personalities. This should be viewed as a springboard for further reading, but it serves a very useful purpose.
