To partially answer the guy who was blaming terrorism entirely on muslims:
The Irish Republican Army, The Sandinista National Liberation front, Continuity Irish Republican Army (CIRA), Communist Party of the Philippines/New People’s Army (CPP/NPA), United Self Defense Forces of Colombia (AUC), PFLP-General Command (PFLP-GC), Revolutionary Armed Forces of Colombia (FARC), Revolutionary Organization 17 November (17N), Shining Path (SL),Liberation Tigers of Tamil Eelam (LTTE), National Liberation Army (ELN), Basque Fatherland and Liberty (ETA).
Not to mention independent actors such as Timothy McVeigh, Terry Nichols, Eric Robert Rudolph, Eric Harris, and Dylan Klebold.
