Which of the following nazi military tactics led to their rapid success in wwii

One way in which Hitler was able to be so triumphant was his exploitation of the suffering economy of the 1930s in Germany. As it was seen in the French revolution, it's easy to change the face of a country when poverty and discontent rest in the heart of a country's citizens. Hitler proposed that the "expansion" of Germany's borders was necessary to Germany's economic improvement so that it could become a "major power." Hope this helps! :)
