Larison argues against western intervention in Libya on the grounds that it might lead to more slaughter:
[O]utside support could easily pave the way for massacres of regime loyalists and those mistakenly believed to be regime loyalists by the rebels. Maybe no one is very concerned about this result, but it’s not something that can be entirely ignored when we’re talking about tying ourselves to the cause of the rebels.
It goes without saying that almost all Western analysts and pundits know very little about Libyan rebels or what it is, besides Gaddafi’s overthrow, that they will want when the war is over. It would be typical if anti-regime forces have a lot of old scores to settle, and tipping the balance in their favor (which is what interventionists are arguing that we do) will make it easier for them to do that. That outcome might happen anyway without outside intervention, but I don’t see why Western governments would want to take an active part in it.
