Editing First World (section)

===Historic===
During the Cold War era, the relationships between the First World, Second World and the Third World were very rigid. The First World and Second World were at constant odds with one another via the tensions between their two cores, the United States and the Soviet Union, respectively. The Cold War, as its name suggests, was a primarily ideological struggle between the First and Second Worlds, or more specifically, the U.S. and the Soviet Union.<ref name=hinds>{{cite book |last1= Hinds |first1= Lynn |title= The Cold War as Rhetoric: The Beginnings, 1945–1950 |year= 1991 |publisher= Praeger Publishers |location= New York |isbn= 0-275-93578-7 |page= 129}}</ref> Multiple doctrines and plans dominated Cold War dynamics including the [[Truman Doctrine]] and [[Marshall Plan]] (from the U.S.) and the [[Molotov Plan]] (from the Soviet Union).<ref name=hinds /><ref>{{cite book |last1= Bonds |first1= John |title= Bipartisan Strategy: Selling the Marshall Plan |year= 2002 |publisher= Praeger |location= Westport |isbn= 0-275-97804-4 |page=15}}</ref><ref>{{cite book |last1= Powaski |first1= Ronald |title= The Cold War: The United States and the Soviet Union, 1917–1991 |url= https://archive.org/details/coldwarunited00powa |url-access= registration |year= 1998 |publisher= Oxford University Press |location= New York |isbn= 0-19-507851-9 |page= [https://archive.org/details/coldwarunited00powa/page/74 74]}}</ref> The extent of the tension between the two worlds was evident in [[Berlin]] -- which was then split into East and West.

The relationship between the First World and the Third World is characterized by the very definition of the Third World. Because countries of the Third World were noncommittal and non-aligned with both the First World and the Second World, they were targets for recruitment. In the quest for expanding their sphere of influence, the United States (core of the First World) tried to establish pro-U.S. regimes in the Third World. In addition, because the Soviet Union  (core of the Second World) also wanted to expand, the Third World often became a site for conflict.

Success lay with the First World if at the end of the war, the country became capitalistic and democratic, and with the Second World, if the country became communist. While Vietnam as a whole was eventually communized, only the northern half of Korea remained communist.<ref>{{Cite web
