Question of the Day

Why is it that the newspapers call warriors against the Sudanese government "rebels," while warriors against the Iraqi government are labeled "insurgents"? Certainly both of these groups deliberately kill civilians. Perhaps "insurgents" operate from underground, whereas "rebels" organize proper armies and control territory? If this is really the distinction that matters, then why did TP hear a reporter on today's All Things Considered refer to Maoist forces in Tibet as "insurgents"?
