Reddit mentions of The Roots of Blitzkrieg: Hans von Seeckt and German Military Reform

> What about economic programs? They turned Germany into one of the largest economies in the world in just a few years.

All smoke and mirrors: vast and unsustainable borrowing and a focus on militarisation with no long term economic benefits.

> All the amazing architecture they produced?

A subjective matter I suppose, but you might be interested in this documentary

The German doctrine which came to be known as Blitzkrieg was in development before the Nazi Party came to power (see James Corum's The Roots of Blitzkrieg). It also worked once against an equivalent opposition: the Fall of France in 1940. It didn't work in North Africa, it didn't work in Russia, it couldn't defend Western Europe.

Under Hitler, Germany went from being the most powerful nation in Europe to the fifth most powerful nation in Berlin.
