Despite the fact that war was still an option, it was believed that the League would both offer and promote other political and diplomatic choices for states such as mediation and arbitration. After the four-year fighting, it was thought that states would prefer diplomatic rather than military options. In this regard, the League was considered a platform where multilateral diplomacy could function.

The primary problem of the League was the assumed equality among its members. As it was a design of the victorious states of World War I, the US, Britain, France, Japan, and Italy were given permanent membership in the Council. 

The weak cohesion among the great powers was one of The League's major weaknesses.

The League did not fairly represent the political and geographical structure of the world.

Probably the most significant weakness of the League was the lack of credible instruments at its disposal to enforce its own decisions.
