I think Bertolt Bretch said something like...
"After the war, the country that lost had it's people starving. The country that won had their people starving too."
My point is that war is not of the interest of the people, but of the interest of the few who are in the dominating sphere, the ones that benefit. Basically convince the people that communication with the other country is impossible and that war is justificable, make some nice rethoric talking about the motherland, patriotism and God, and you got your war all set.
As for me, I can understand war when a country is invading another. If you are getting invaded by someone you don't like, then you must obviously fight back. I don't think the invasion is justified, but the defense is.
