Hitler's+strategy

 Hitler was able to take most of the world by surprise by using very aggressive and unconventional tactics in an "all or nothing" military campaign. Hitler intended to defeat one enemy then have a time of peace then defeat another enemy, thus giving a chance for his army to replenish its supplies. In battle, his military forces used what is now called term blitzkrieg, or lightning attack, to take the enemy by surprise. the reason this was so successful was that, during World War I, battles took a long time, sometimes months or years, and involved the digging of trenches, digging in of artillery, and many, many charges across no-mans land to gain, maybe a foot of ground. With the improvement of the tank and the ground attack/bomber aircraft, Hitler was able to keep his army highly mobile while still retaining a massive amount of fighting force. Hitler was also the first to use "combined forces" attacks, using airplanes, tanks, and troops to achieve his goals. These new tactics took Hitler's enemies by surprise, allowing him to win many battles before the Allies could come up with an effective counter to these tactics.
