Why did the Wall Street crash make things worse between the countries?

The Wall Street crash of 1929 intensified economic turmoil globally, leading to a severe contraction in trade and financial relations between countries. Many nations adopted protectionist policies, such as tariffs, to shield their economies, which further stifled international commerce and deepened the Great Depression. This economic strife fostered resentment and distrust among countries, contributing to political instability and the rise of extremist movements. As nations struggled to recover, the lack of cooperation and collaboration exacerbated tensions, setting the stage for future conflicts.
