On a tangentially related note, this documentary series from BBC4 is a fascinating insight into the decision making process the US went through over dealing with foreign mass atrocities over the past 40 years: Iraq, Bosnia, Rwanda, Syria etc.
Warning: they do not hold back with the imagery of these events.
Did they also go into mass atrocities committed and initiated by the US? If you go around lighting fires and then come back around to put them out after donning an official uniform, should others consider you a fire fighter or an arsonist?
Is there a single instance covered that wasn't a situation the US directly and purposely had a hand in creating?
