At the risk of self-promoting, read my memoirs, especially the final three chapters on Rwanda regarding intelligence reporting, analysis, and strategic warning concerning the prospects for a larger war in central Africa.

Journey into Darkness: Genocide in Rwanda, TAMU press 2005. Your library probably has it.

I also suggest that you read this article in SWJ magazine:
Guerrillas From the Mist: A Defense Attaché Watches the Rwandan Patriotic Front Transform from Insurgent to Counter Insurgent
