Why did some countries view with suspicion the setting up of the legue of nations?

Some countries viewed the establishment of the League of Nations with suspicion due to concerns about its effectiveness in preventing future conflicts, particularly after the failures of the Treaty of Versailles. Nations like the United States were wary of entangling alliances and the potential for being drawn into international disputes. Additionally, some countries felt that the League favored the interests of major powers while neglecting smaller nations, leading to fears of bias and ineffectiveness in ensuring collective security. These apprehensions ultimately undermined the League's authority and functionality.
