Context

“The way chosen by the United States was plainly marked by a few clear precepts, which govern its conduct in world affairs. First: No people on earth can be held, as a people, to be enemy, for all humanity shares the common hunger for peace and fellowship and justice. Second: No nation's security and well-being can be lastingly achieved in isolation but only in effective cooperation with fellow-nations. Third: Any nation's right to form of government and an economic system of its own choosing is inalienable. Fourth: Any nation's attempt to dictate to other nations their form of government is indefensible.” source
