Peacekeepers For Syria?

Assad appears to have rejected an Arab League proposal to send in neutral troops to end the violence. Hayes Brown isn't shedding any tears:

Fun fact: when launching peacekeeping missions, it helps when there’s a peace to keep. There clearly is not such a peace currently, not with anti-aircraft weapons being fired into random houses in Homs. And there will be even less of one once the “material support” to the [Free Syrian Army] comes through. Who honestly believes that sending lightly armed forces into an increasing civil war situation is a good idea?

Neither is Mark Goldberg:

What peacekeepers cannot and will not do is wage war. By “wage war” I mean invade and occupy a country. They cannot shoot their way into a country that does not want Blue Helmets. They must be invited to the country by the host government…If, at some future point the Assad regime agrees to a ceasefire and invites a peacekeeping force to monitor and help implement the ceasefire or peace agreement then we can start talking about a peacekeeping force. For now, though, the idea is basically a non-starter.
