Consider Libya

Was the intervention worth it? Chris Bertram thinks not:

One reason to intervene was to prevent severe human rights violations, including the possibility of massacre in Benghazi. Well a cruel and vicious regime with a dreadful human-rights record has gone, but seems to have been replaced by a squabbling coalition of militias, little inclined to submit to the authority of a central government, with Ghaddafi-loyalists making a comeback. Moreover, said militias seem to be engaged in serious human rights violations themselves, abuses that have been going on pretty much since “victory”. Those who were most enthusiastic for intervention don’t seem to be saying much about these worrying recent developments. An intervention predicated on defending human rights certainly won’t have been justified if the successor regime ends up presiding over similar persecutings, detainings, torturings and killings itself.
