war is just a way for businesses to shore up their falling profits. destroying another country gives victor companies chances to rebuild, which temporarily shores up profit rates because so much capital is destroyed and the creation of new capital during the windup phase actually increases the rate of profit for a little bit. there are other techniques as well. that said, the corruption was so rampant that they didn't even execute that well. either way the human costs of continuing to run capitalism as usual are staggering and wars are one of the many facets of that. all the other explanations and media outrage etc and just cover stories to make it palatable for the public, which has already believed the big lies about democracy and freedom existing under capitalism
