War is good for lots of things, actually. Profits - as long as not too much gets destroyed. Propaganda. Keeping the poors further in their place. Your election chances, if your war is going well. And if it's not going well? Send some more boys into the meat grinder! Why not? Ain't you or yours, and "surges" are good for your poll numbers.
Where else can you get so many medals and pins? If you're lucky - but hey! Someone's got to be lucky. Could be you or me! Roll the dice and storm that building. You could be a war hero!
The donkey didn't get a choice. But then, no animal does, when a war's on. Except the rich ones.
