Wars doesnt harm every country. i think some of the country gets benefited because of it.
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.
That war is a purely destructive process, no one argues. But there is a more important indicator - the conclusions and reaction.
In technical terms, it is not so much the errors in the system that are critical as the lack of reaction of the system to these errors.
I.e. it is very important - what will be the reaction of the world, in order to prevent the recurrence of similar problems in the future. Because in addition to the huge number of human casualties and destruction of entire regions in Ukraine, this war has created real global problems in the world economy. It is true that this is already a topic of economic terrorism, but the world must develop solutions against it as well.
