According to the article, there is no conclusive evidence to suggest that wars occur more frequently during economic downturns. While some countries may resort to military expansion during times of economic crisis, conflicts can occur at any stage of the business cycle. The real cause of war is not economic optimism or competition for monopoly capital, but rather downward pressure on the economy, which can create a sense of urgency and lead to military solutions. Even during periods of economic expansion, countries may face downward pressure on the economy and resort to war as a solution. Therefore, while the business cycle may influence the likelihood of war, it is not the sole cause of conflict.
