Mike,

I do not think that what happened to Gaddafi can be used as a generality.
Look what happened to Bagbo: trained troops arrested him and followed orders.
Look what happen to anyone with FARDC (DR Congo) and SPLA (South Sudan) (two conventional armies): you get tortured and executed without any legal ground, just for fun. And they receive training, at least for FARDC, from 5 major military powers; US, Belgium, France, South Africa, China, Angola.

The world is better with the rules than without. Application is, at least for the momment, to be perfected.
