Answer 2

The biggest conflict in history, by quite some margin, is World War 2. There is quite some separation between the War in the Pacific & the War in Europe, but of course both the US & Britain, and others, notably the Australians, were involved in both & from 1941 to 1945 were simultaneous.

Answer 3

WW2.

Let me add that because World War 2 was the biggest, is simply because Hitler was a very powerful man in that time. He hated the Jewish culture's, he became a dictator and ruled over Germany killing many Jewish people for what the believe in. The Americans(along with our allies) couldn't take the Horror and sent many soldiers to take out Hitler.

Many years fighting the war cause Hitler to realize that this war will not be won, he and his wife, Eva Braun, comitted suicide. Though there are many theories on how Hitler died, people have now decided that the cause of his death was a gunshot to the head on Monday, 30 April 1945 in his Führerbunker in Berlin.
