Not that anyone had any hopes that the Arab delegation would succeed at mediating between the pro-government and anti-government factions in Lebanon, but there are more early indications that they are predestined to fail. FOr example, NowLebanon reports (emphasis mine):
12:00 Head of airport security Wafiq Choucair and resigned Foreign Minister Fawzi Salloukh await the arrival of the Arab Ministerial Committee at Rafik Hariri International Airport.
If true, this is more needless display of force, this time of the political kind. I read this as juvenile behaviour aimed only at "rubbing it" in the face of the government's (useless) Arab allies, reminding them of the facts on the ground. In the same vain, Future TV (whose objectivity at this point is more in question than it was before) is also reporting a heavy presence of Hizbulla members along the airport road. This kind of behaviour will only serve to deepen the rift between said allies and the Syria/Iran axis. Unlike some hopeful observers, I don't see any of what happened in the last few days as hastening a solution to the political crisis, but only precipitating it - highlighting the nature of the events of the last few days as a coup - and expanding the crisis further both locally and regionally.
I could be wrong. In fact, I hope I am wrong, but I doubt it.
