War Drawing

During this same post-war period, with the aim of further delegitimizing war as an acceptable and logical extension of foreign policy, most national governments also renamed their Ministries or Departments of War as their Ministries or Departments of Defense, for example, the former US Department of War was renamed as the US Department of Defense.
In 1947, in view of the rapidly increasingly destructive consequences of and costs of the newly developed atom bomb, the initial developer of the concept of this bomb, Albert Einstein famously stated, "I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones." Fortunately, the anticipated costs of a possible third world war are currently no longer deemed as acceptable by most, thus little motivation currently seems to exist on an international level for such a war.
