In War Before Civilization, Lawrence H. Keeley, a professor at the University of Illinois, says that approximately 90–95% of known societies throughout history engaged in at least occasional warfare, and many fought constantly. Despite the undeniable carnage and effectiveness of modern warfare, the evidence shows that tribal warfare is on average 20 times more deadly than 20th century warfare. At one battle lost in 1857 among the Mohave-Yumas, 49.6% of combatants were killed; in a great Aztec battle fought in 1478, 87.1% of 24,000 combatants were killed, while 100% of combatants were killed during the Blackfoot Indian raid which annihilated the Assiniboins in 1849.
The Human Security Report 2005 documented a significant decline in the number and severity of armed conflicts since the end of the Cold War in the early 1990s. However, the evidence examined in the 2008 edition of the Center for International Development and Conflict Management's "Peace and Conflict" study indicated that the overall decline in conflicts had stalled.
Recent rapid increases in the technologies of war, and therefore in its potential destructiveness (Mutual assured destruction), have caused widespread public concern, and have in all probability forestalled, and may hopefully altogether prevent the outbreak of a nuclear World War III. At the end of each of the last two World Wars, concerted and popular efforts were made to come to a greater understanding of the underlying dynamics of war and to thereby hopefully reduce or even eliminate it all together. These efforts materialized in the forms of the League of Nations, and its successor, the United Nations. Shortly after World War II, as a token of support for this concept, most nations joined the United Nations.
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.
