And what are the benefits that other countries get from war, if not the chaos, fear, and trembling of some citizens, which can cause them to have some health issues? Even if a country does win a war, it doesn't make the economy better during that time. Things don't normally work well for that period until war is over, and there might even be some restrictions during that period, which can make some workers stop working, some companies stop production, and short down at that moment. If war lingers for so long, it can cause more harm to the economy of that country.
