Introduction

World War II started because of many separate reasons. One of the original starts of the war was the nonaggression pact signed between Germany and USSR. They promised each other land that they were unable to fulfill. Germany started a new military tactic called Blitzkrieg, and then began destroying other countries. Then the United States got involved in the war because of Japan, and them bombing Pearl Harbor. However, Japan was later was no threat due to the United States dropping the Atomic Bomb.
