What Report reported a 40% decrease in the number of armed conflicts being waged around the world once the state of geopolitical tension after World War II between powers in the Eastern Bloc and powers in the Western Bloc came to a close?
Cold War The Cold War was a state of geopolitical tension after World War II between powers in the Eastern Bloc (the Soviet Union and its satellite states) and powers in the Western Bloc (the United States, its NATO allies and others). Historians do not fully agree on the dates, but a common timeframe is the period between 1947, the year the Truman Doctrine (a U.S. foreign policy pledging to aid nations threatened by Soviet expansionism) was announced, and 1991, the year the Soviet Union collapsed.
Yugoslav Wars The Yugoslav Wars were a series of ethnically-based wars and insurgencies fought from 1991 to 1999/2001 in the former Yugoslavia. These wars accompanied and facilitated the breakup of the Yugoslav state, when its constituent republics declared independence, but the issues of ethnic minorities in the new countries (chiefly Serbs, Croats and Albanians) were still unresolved at the time the republics were recognized internationally. The wars are generally considered to be a series of separate but related military conflicts which occurred in, and affected, most of the former Yugoslav republics.
