How to Lose WWII: Bad Mistakes of the Good War

There had never before been a war on the scale of World War II. The sheer size of the conflict, or even the immense scope of a single battlefield, multiplied the effects of both brilliant and bad decisions. When millions of men are attacking in a Russian offensive or thousands of aircraft are dueling in the skies over Europe every key decision had dramatic, and often disastrous, results.
Among the catastrophic mis-steps:
* Poland's lack of preparation for the Nazi invasion
* Germany fails to take Britain out of the war at Dunkirk
* Russia plays Goliath to Finland's David
* Allied forces get trapped for four months on the beaches of Anzio
* Germany wastes its costly development of jet power
