Even in the area of security, the UN retains an important role. The original 1945 concept of collective security, by which states would band together to deter and punish aggressors, failed because the Soviet Union and the West were at loggerheads during the Cold War.
即便在安全方面，联合国仍然发挥着重要作用。在1945年制定的最初的集体安全概念里，各国应该联合起来阻止并惩罚侵略者。这一概念由于苏联和西方在冷战时期的敌对而未能实现。
