Yes war is a monster because war brings a huge loss in the economy of a country. so war is also known as evil and many peoples die in the war because of war between their countries .War is not a peace but Today because of science man is too powerful and thus using science he can conquer the world also.we know that War is evil and horrible, but still we need war. War has several beneficial outcomes as far as the whole of humanity is concerned; advancing technology, population control, and the spreading of cultures. Even if you disregarded these war would still be required due to the existence of men and people that are unwilling to change, unwilling to compromise, and the worst of all willing to force their wills on others. If not for war we would all be ruled by despots spewing lies at us with such force as to control us, with no war the liars would rule. In a world where liars ruled humanity would stagnate with little interest in advancing technology or building a better world. History has taught us that humans are inspired to great heights by danger and fear and not when complacent and content.
