The major negative of war is that it is destructive.  War destroys wealth as countries use hard-earned tax dollars to buy things like artillery shells to blow up things like tanks that were made with other hard-earned tax dollars.  War destroys property and economic capacity.  In WWII, places like Germany and Japan experienced heavy bombing and other destruction of their cities, impoverishing people and reducing the countries’ ability to grow economically.  Most importantly, war destroys people.  War kills and maims horrific numbers of people, military and civilian alike.

There are at least two main positive aspects of war.  The first is that war can bring about technological development.  Countries are willing to spend massive amounts of money developing war technology that can later be put to civilian use.  An example of this is the fact that civilian airlines were helped tremendously by the development of heavy bombers in WWII.  The second is that war can, at times, put an end to injustice, thus improving the world.  WWII is an example of this. By going to war, the Allies were able to stop the spread of Nazism, which was a clear example of evil and injustice in our world.
