> Are europeans responsible for the deaths and slavery in libya? And americans are responsible for the deaths in the middle east? When do we cut those populations out?

Speaking as an American, I'd say "yes". At least for the citizens who were adults at the time and were aware.

I'm suspicious of any moral framework that's hand-tuned to paint some persons as upright.

I think we just shy away from the fact that we are in fact culpable, so we look for rationalizations.
