The assassination in 1986 of Olof Palme, a distinguished international statesman, remains to this day an unsolved mystery. While in some ways resembling the puzzling features inherent in the assassination of President John F. Kennedy, the continuing mystery has a deeper significance that the authors of this work seek to probe and elucidate. Any examination of the Palme assassination has to be conducted with reference to an extremely complex set of international factors. It is in this milieu that Palme found a special role for himself as an international statesman, seeking to mediate some of the lesser though deadly wars, in particular the Iran/Iraq conflict. Palme the Peacemaker had many enemies and a consideration of the role which may have been played by some of them is carefully examined, by a reference to a theoretical schema of the assassination phenomenon, of the motives and modalities of each of the likely candidates. There were many who had no wish to see an early settlement of the Iran/Iraq ward. Some of these were nation states with an animus against one or both of the combatants, Some hoped that hostilities would exhaust the two contenders, while others, such as international arms dealers, sought to profit. The authors see the Swedish Prime Minister as an unfortunate victim of a largely clandestine clash of forces: it is their identity that continues to elude investigators. The authors examine all the evidence, present their own case on these arcane matters, leaving it to the readers to come to their own conclusions.
