There is no happy ending in war. Only relief once its over (which probably won't exist if there is ever a WWIII) and then trying to cope with the losses.
Yes, exactly, that's why war is the most obvious testimony to human stupidity and I hope that, if there is justice dealt after death, the people who had to pay thre greatest price thanks to the folly of their fellow man get a chance to hold judgement over them and repay them their "kindness".
