Even after the United Nations (U.N.) was established, wars have continued to occur in the world. The wars which have taken place between U.S.A. and Vietnam, Iran and Iraq, Israel and Palestine, Iraq and Kuwait and India and Pakistan have led to heavy destruction of life and property.

The super powers of the world have made innumerable atomic experimentations. There is such a large arm our of destructive weapons with U.S.A., Russia, China and other countries that the whole world can be ruined. These countries have added extremely dangerous chemical weapons to their armoury. It will not take even a little time for a world war to occur, even from a small war, and if the World War III takes place, the entire property and wealth of people will perish. There will be complete devastation of the entire world in a fraction of a second due to these highly destructive manmade weapons. The world has witnessed devastation caused due to two world wars. Therefore, weirs should be avoided at all costs in order that the very existence of mankind is taken care of.
