The United Nations was formed in response to WWII and the fact that the League of Nations had failed. Members of the League realized that the idea of a collaborative organization would work, but things needed to be changed so that the organization would be more fair and be much more representative of the power structures that were inherent in the international system. This time, they included Germany in the organization instead of leaving them out and changed the voting structure as well. The UN was created much like the League of Nations to stop the catastrophe of full out war from occurring again.
