The Rabid Tiger Project believes that a nuclear war is most likely to start in Africa. Civil wars in the Congo (the country formerly known as Zaire), Rwanda, Somalia and Sierra Leone, and domestic instability in Zimbabwe, Sudan and other countries, as well as occasional brushfire and other wars (thanks in part to "national" borders that cut across tribal ones) turn into a really nasty stew. We've got all too many rabid tigers and potential rabid tigers, who are willing to push the button rather than risk being seen as wishy-washy in the face of a mortal threat and overthrown. Geopolitically speaking, Africa is open range. Very few countries in Africa are beholden to any particular power. South Africa is a major exception in this respect - not to mention in that she also probably already has the Bomb. Thus, outside powers can more easily find client states there than, say, in Europe where the political lines have long since been drawn, or Asia where many of the countries (China, India, Japan) are powers unto themselves and don't need any "help," thank you. Thus, an African war can attract outside involvement very quickly. Of course, a proxy war alone may not induce the Great Powers to fight each other. But an African nuclear strike can ignite a much broader conflagration, if the other powers are interested in a fight. Certainly, such a strike would in the first place have been facilitated by outside help - financial, scientific, engineering, etc. Africa is an ocean of troubled waters, and some people love to go fishing.
