Why did member countries of the league of nations not provide soldiers to the league?

Member countries of the League of Nations often hesitated to provide soldiers due to a combination of national interests, lack of commitment to collective security, and the trauma of World War I. Many nations were reluctant to engage in military interventions that could lead to further conflicts or entanglements. Additionally, the League lacked its own military force and relied on member states to contribute troops, which often resulted in inaction when faced with aggression. This failure to enforce measures weakened the League's credibility and effectiveness in maintaining peace.
