The author has produced what is surely the last word in explaining the rise and fall of Nazi Germany. This is an economic history, and this allows the real story of the Third Reich to be told. Like all history, the prosecuting of war really depends on the ability to raise and sustain a war machine - this has been the case for most of history. By concentrating on this fundamental fact, the book clarifies the actions of the Third Reich and it's leaders. Essentially, Germany in 1920 had the choice of either accepting it wasn't a major power and becoming a satellite state of the US, living as an exporting economy, or going down the road of war and becoming a world power and exploiting Europe as a conquered empire. Many in Germany at the time refused to accept the former, and through Hitler they made there bid to change the course of history. The author is careful to point out that although this course was fundamentally unsound in view of Germany's real position, there was a lot of logic behind the Nazis world view. Germany was critically dependent on imports of food and materials, it owed huge amounts of money to the US, and had foreign troops on it's soil. Hitler offered what looked like a credible alternative to the man in the street.
The book carefully explains how the Nazis built their war economy, and why it was used at the time and the way it was. Whenever it looked like Germany was losing it's advantage through early mobilisation, war was the only alternative to slow strangulation by naval blockade and air warfare.
After the entry of the US into the war in 1941 by offering aid to the UK, the Nazi leadership knew it had to win the war by 1942. (This thinking made the invasion of the USSR inevitable to the Nazi leadership, who were all to aware of the potential of strategic bombing).
To the Nazi leadership, a showdown with the US/UK was always going to happen, and it was better to happen on their own 'best terms' - i.e. before the US and UK could build an air fleet to destroy German industry. If all potential threats on the continent could be eliminated first, the Luftwaffe could then be built up into a force to protect the air over Europe.
One interesting thing the book also points out is the importance of the UK's blockade of Europe. Basically, Europe is dependent for imports of everything - food, materials etc. With the UK's naval blockade the economy of France (and most of Europe) basically collapsed by the end of the war, with Germany relying on the plundering of conquered countries (and slave labour) to keep financing the war. The rules of war in Europe have not changed since Napoleons time. An effective blockade of the continent soon causes huge problems, forcing Germany or whoever to look at desperate measures (invading Russia) to 'break out' of the blockade and find alternative sources of food/materials.
The author also explains the timing of the holocaust, and the timing of this too has an economic basis - food. In 1941/2 Germany found itself with too many mouths to feed and blockaded. The Nazis decreed that Germans would be the last to starve (as they had in 1918).
Unbelieavably it decided to kill millions of people in Poland to free up food, and then to mass starve the population of the western USSR. There was a plan to starve to death 20 million people as the policy of the German armed forces. This was planned and coordinated at the highest levels of both civilian and military authorities. A terrible story.
