History is unpredictable indeed. As our knowledge about the events grows, as our views on the relationships between the nations develop, we tend to adjust or to change altogether our understanding of the events and personalities in the distant or not so distant history.
The Churchill, Hitler, and "The Unnecessary War": How Britain Lost Its Empire and the West Lost the World by Patrick J. Buchanan very much turns currently acceptable image of Sir Winston Churchill inside out, and puts the role of the British Empire in both First and then Second World Wars into a very different prospective.
The author who is a former senior adviser to three US Presidents himself, after assessing new facts, letters and protocols, and re-assessing some historian cliches, paints very different picture of the role of the British Government and personally Sir Winston Churchill in the course of both wars.
He points out that Germany has not been an aggressive nation the years preceding the WWI. He makes a point of the whole mess having been in large part a consequence of the UK foreign doctrine assuming that no single country on the continent should be more capable that the Britain herself. This and Sir Winston Churchill's personal deeds, in author's opinion, caused entire European catastrophe resulted in the Europe losing it's role in geopolitics and making itself dependable on American good (or otherwise) will.
Whether you revere Sir Winston Churchill or not, the Churchill, Hitler, and "The Unnecessary War": How Britain Lost Its Empire and the West Lost the World
would be an eye opener, and definitely a must read book for all interested in history.
