War of course is a disaster that can occur in the long run, countries that are at war certainly need a long time to recover, as happened in the Balkan countries where there was a war about 30 years ago but the trauma is still felt today, but war also brings benefits to other countries that sell any product in a warring country, and usually the supplying country must be prepared to take risks if the country is in debt and pays in the long term.
It's devastating that there is always one who will suffer more and neighboring countries benefits. There is nothing to be happy with war aside from getting out from it. Tho peace and money can possible be gained from war, children and the innocent people always suffer the most while those in the position who decided to make the war happen are sitting comfortably. Good leadership will prevent this kind of crisis, I believe.
