Men fought wars since civilizations existed. I have heard of a number of flourishing civilizations which were lost to wars. Trojan War, comes first to my mind. People fought for Power, Pride or just for the heck of it.. To prove that they are great... After all "War is a Drug", as Hurt Locker says it.
I was never one to support wars, but that was not my point to begin with. When wars were fought before technology grew out of bounds, people had to fight with some normal arms and were involved in man-man combat. Considering the current scenario, and how wars are being fought, I feel that those wars are way better than the wars that are being fought today.
With all the cutting edge technology available, ala Nuclear bombs, the damage is no longer limited to the war itself. It spreads over to the ecological system, Damage to terrains, Ozone system, Wild-Life.. And wars nowadays seem to be like long running episodes.
If you really want to war that much, please go back to basics... Use some spears, bows and arrows, swords and keep the other stuff out of it.. That should atleast limit the damage. Atleast then, we can have some peaceful wars...
I must be dreaming though.. That is not gonna happen...Since power is a drug too... and you can't ignore it, once you got addicted to it..
