War make business owners not to make profits from their businesses because customers will be running for their dear life or managing the ones they have bought before the war started from the country.
You can see many countries war has reduced their economy to zero just because they allow war to involve between them and their neighboring country, no business will be moving well in such area, and their suppliers will be afraid to supply goods to those that demand for the goods because no one want to lose his life for war.
It will take some years before Russia and Ukraine businesses owners can recover from the damage of their businesses for the war that is affecting them, and it will make other countries to know that war always bring damage to the economy.
War indeed has a profoundly disruptive impact on economies and individual livelihoods. When conflict arises, normal economic activities often grind to a halt. Business owners face plummeting profits as customers prioritize safety and survival over shopping. Additionally, the uncertainty and danger associated with war zones discourage suppliers and disrupt supply chains, further strangling business operations.
