This quote (from Lord of War) really encapsulates a lot of what you say:

> Yuri Orlov: [Narrating] Every faction in Africa calls themselves by these noble names - Liberation this, Patriotic that, the Democratic Republic of something-or-other... I guess they can't own up to what they usually are: the Federation of Worse Oppressors Than the Last Bunch of Oppressors. Often, the most barbaric atrocities occur when both combatants proclaim themselves Freedom Fighters.
