What can we conclude from the Second World War?

There are
numerous things that we can conclude from World War 2. Among them is that we shouldnt use atomic
weapons and that Nazism and fascism are destructive. The main thing to understand, however, is
that warfare has vastly changed and technology is the new face of battle.

To
the first point, warfare prior to the World Wars was typically done in lines and straight on,
meaning that a sheer numerical advantage would usually lead to victory. These wars created
trench warfare and eventually led to guerrilla warfare, an entirely different strategy based on
more advanced tactics.

Technological dominance is the second conclusion of
importance, and one that America and the Soviet Union both took to heart immediately following
the war. Germanyand then later the United Statesproved that the more technologically advanced
nation would have a supreme leg up on the competition. U-boats, smaller tanks, and improved
airplanes led to Germanys dominance of the European sphere of battle, but American planes,
warships, submarines, code breakers, and eventually nuclear weapons prevailed mightily, showing
that technological development was paramount to victory in an international
conflict.
