There is still considerable debate in Japan about Japan's conduct before and during World War Two, culminating with Japanese society's continued refusal (from ordinary people to government) to come to terms with and apologize to the nations that Japan attacked or colonized before and during World War Two. The United States has refused to apologize to Japan for dropping nuclear bombs on Japan during the Second World War. Recently, the USA President said he thought the USA owed Japan no apology for having used the bombs fifty years ago, based on the facts before him.
Though not an aggressor nation during World War Two, there is some concensus that the United States could apologize to Japan for having used nuclear weapons against Japan because: this marked the only time nuclear weapons were used against a people; nuclear weapons are totally indiscriminate and massively destructive, far beyond the destructive capability of conventional warfare - they should never have been used, whatever the circumstances; tens of thousands of the nuclear bomb survivors have died long after the conflict from cancer and other radiation related-sickness because of the long-term radiation effects of nuclear bombs, whether on people or the environment.
The Encyclopedia of World Problems and Human Potential is a collaboration between UIA and Mankind 2000, started in 1972. It is the result of an ambitious effort to collect and present information on the problems with which humanity is confronted, as well as the challenges such problems pose to concept formation, values and development strategies. Problems included are those identified in international periodicals but especially in the documents of some 60,000 international non-profit organizations, profiled in the Yearbook of International Organizations.
The Encyclopedia includes problems which such groups choose to perceive and act upon, whether or not their existence is denied by others claiming greater expertise. Indeed such claims and counter-claims figure in many of the problem descriptions in order to reflect the often paralyzing dynamics of international debate. In the light of the interdependence demonstrated among world problems in every sector, emphasis is placed on the need for approaches which are sufficiently complex to encompass the factions, conflicts and rival worldviews that undermine collective initiative towards a promising future.
Non-profit, apolitical, independent, and non-governmental in nature, the UIA has been a pioneer in the research, monitoring and provision of information on international organizations, international associations and their global challenges since 1907.
