Hydrogen Bomb

It is a well known fact that during the Second World War, Nazi Germany was working towards developing a nuclear bomb which they could deploy over continents. Nearing the end of the war, the US managed to develop the atomic bomb first and they dropped two of them over Japan, therefor ending WW2. At the end of the war, both the US and the USSR rushed to their own development of thermonuclear weapons of mass destruction.

The key difference between an atomic and a hydrogen bomb is that the hydrogen bomb doesn't use fission but fusion. An H-bomb requires a small A-bomb to ignite in order to set off, while an A-bomb can be used as a weapon itself. In either case it is a very, VERY powerful weapon.

WW2 Allied Bomber

The role of airplanes during WW2 was of extreme importance, much more important than WW1. In the First World War the role of airplanes was limited to biplanes equipped with machine guns and manually throwing grenades. They couldn't reach great heights nor great speeds, but nevertheless they remain in memory, usually associated with Red Baron.

In the Second World War, airplanes had a great increase of use, especially in the Luftwaffe in the German Blitzkrieg tactics. Anything from air raids, great fights such as the Battle for Britain, intense maneuvers, observation operations, paratroopers deployments, massive bombing campaigns and the drop of nuclear bombs over Japan marked the air actions of WW2.

German Soldiers WW2

The Second World War was the biggest armed conflict of all times, involving a great number of nations, people and conflicting ideologies. It officially started on the 1st of September 1939 by the German invasion of Poland, but the annexation of Austria and a few other incidents already happened before.

It is considered that the war was initiated by the complex German situation after the Versailles Treaty. Bad politics, economy, the Great depression all influenced on the rise of extremist nationalism. The Nazi regime and the soldiers of the Wehrmacht were responsible for a great number of war atrocities, genocide and war crimes.
