With the Brexit debacle threatening to take us and Europe back to a more inter-war state of affairs books like this are probably needed more than ever. Perhaps not so much by us military history nuts, so much as to remind people who may otherwise forget or just be plain ignorant, of the broad brush-stroke history of the fascinating but appalling events of WWII.
O'Kelly succeeds in covering all the major theatres and campaigns, albeit in very broad simplistic terms. And it's a pretty well balanced account, that could be read in a single day. For my 'general readership' Amazon UK review I scored this four out of five. Here on my more special interest blog I'm scoring it three and a half 'kreuz, which accords more with my own personal take on it.
PS - Having said all of the above, I also think it's a quite good/handy thing for even grizzled old dogs like me to have a concise single volume précis of the massive cataclysm that was WWII. Reading this helped me zoom back out momentarily from the maelstrom of minutiae that most of my WWII reading usually subjects me to. It also helped remind me of things I want to read more on, such as the Dieppe raid, Kursk and the battles for Kharkov, or Operation Dragoon.
* There are also two appendices: one on 'Meetings of the Great Power Leaders', the other a timeline.
