Why was World War 2 different from World War 1?

Answer 1

WW2 was a war of fire and maneuver on the ground and in the air it

evolved into the concept of total war.

While it was initially believed to be a continuation of WWI's attrition tactics, where basically there was little movement, which spurred France into action with the building of the Maginot line, basically a big wall, Hitler realized that Nazi Germany had a weak, though technologically advanced military, and that the best way to utilize this was to make wuick "lightning" attacks, hence the word Blitzkrieg. The technology was massively improved upon, making machine guns, artillery, air power, and various other killing machines all the more deadly. Also, the Axis powers were much more Germany based, mainly because Germany basically annexed everyone else.
