There is unnecessary War and Necessary War. What are examples of unnecessary Wars, well The Revolutionary War, The American Civil War, The War in Kosovo and I think the Korean War .
What are unnecessary and immoral wars, The War against the American Indian culture and way of life, The War against Mexico, The Vietnam War and the Iraq War,the killings of millions of hindus in India by Mughals are all wars that should not have happened at all.
So its not that all wars are unnecessary but yes most of them are.
