The Second World War created many apprehensions as the world had not witnessed catastrophe of that scale before. It raised many concerns for global peace, and led to the creation of United Nations (UN) primarily to prevent the world from the scourge of the Third World War.

Since then, we have witnessed many ups and downs in the global order. There have been times when somehow war of a global scale was prevented.
