From the title above, readers might think that there are positive effects of war on citizens (civilians). Here I emphasize "there will never be a good reason in a war".
To prove it, we can look at countries that have been at war for decades, which have taken decades to rebuild the rubble of suffering from what a war has produced. Whatever the reason, war is not a decision to resolve a dispute. Maybe we can put aside the financial loss as a starting point for a war. For example, the Russia-Ukraine war, when the war started, world oil prices immediately jumped (you can guess what caused it, I'm sure).
Likewise when a war ends, even though a country gains memories, and rebuilds a country that was attacked, but one thing that he can't wake up to from the beginning, namely the psychological condition of the citizens affected by the war, moreover the children who have lost their parents. . It is not an easy thing to manage the psychological condition of society. Perhaps the best solution of all this is that there should be no war.. /
