Destexhe has published a number of books, including one, translated into English, dealing with the Rwandan genocide. His book deals mainly with historical antecedents leading up to the mass killings in 1994 and who was to blame. Afterwards, his analyses of that era have been used in many parliamentary enquiries and investigation commissions. A 2004 exchange between Destexhe and Canadian general Roméo Dallaire, the military leader of the UN peacekeeping force in Rwanda, can be seen in the CBC documentary "". Destexhe stated that Dallaire failed to protect his troops and cost the lives of ten Belgian Blue Helmet soldiers in UN service.
