Why wasn't the League of Nations effective in opposing fascist aggression in Europe North Africa, and Asia?

The League was not effective in opposing fascist aggression in Europe North Africa, and Asia for a number of reasons.

Firstly, the League could ask member countries to stop trading with an aggressive country. But this did not work because countries could still trade with non-member countries. In addition to that, the League of Nations was unable to act quickly. The Council of the League of Nations only met four times a year and decisions had to be agreed by all nations. This signified that the League could not act quickly to stop an act of aggression.
