I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones.
Albert Einstein

Wars Fought With The Weapons of Their Times
Wars among nations or clans have been the most devastated part of whole of the “Human Society“. Throughout the centuries, wars have defined our possessions of materials or say, even territories. Albert Einstein has shown with his quotes that how the unparalleled wars are uncertain in nature with the use of different weapons.
However, his quote has a deeper meaning behind. During the second world war (from 1939 to 1945), he got to realize the intensity of Nuclear weapons. Russia waged war over Ukraine recently. International Relations in such scenario is not suitable for peace at all. With passage of time, the situation may worsen. The whole world has an eye over this development.
His quote clearly describes his understanding about the propensity of weapons, their use and the human nature as well. Use of weapons in Hiroshima and Nagasaki was a new chapter in history, even Einstein got sacred to know about such devastated impact on Japan. Since then, many international treaties and agreements have taken place. This is in regard to curtail the developments of Nuclear Weapons all around the globe.
