Ardy, numan's post pretty much summarizes what I've been saying.

Wars are started with economic motivation. There are profiteers, as numan pointed out, and there are motives of economic hegemony on the part of the aggressors.

Whether or not the goal of economic hegemony is reached depends on the outcome of the war. Those who initiate it do not know the outcome beforehand.

So, given those two aspects, there always seems to be some economic benefit, whether it be to the profiteers or whether it be through economic hegemony, or both.

I don't know how else to explain it.
