Robertson: You have this whole opposition that hasn't even engaged yet with the opposition outside of the country and the opposition that's fighting there. So to see how they're going to get together and govern together is very difficult. ... Any sort of sense of these opposition groups want to coalesce around democracy, those are not the indications we have at the moment. They're talking about "We won't stop until we get rid of Assad." These are not people who are showing a great ability to compromise so far.
How will the world respond or help or engage with the new Syria?
Paton Walsh: I think, in many ways, the process of that is under way, with the U.S. trying to influence a government in exile (and) many opposition figures gathering in Doha or Turkey to try and work out how that government would look like.
But the problem is that might not relate to the daily struggles people are facing on the ground inside Syria after what would be a two-year long war. And bridging that gulf between the men in suits in five-star hotels ... and people on the ground who may be starving or missing the roof of their house from shelling is going to be the enormous challenge.
Robertson: Distrust is endemic region-wide. The distrust of the United States and Europe is deep-rooted in the culture in Syria already from 40 years of Assad rule, from watching what's happened in other Arab countries, from hearing what radical Islamists say what the West is trying to do with Islam.
All these things have been fomenting in the background. And now you have a scenario where the West hasn't come to the aid of the Syrians, so people are deeply angry.
I don't think we're going to find friends quickly in Syria. We're certainly not going to win trust there quickly. And that's going to make whatever we want to see -- the international community wants to see happen in Syria -- that's going to make it much, much harder to achieve.
