what syria needs and what is realistic are simply too far apart. ideally what needs to happen is a real election, with the baathists banned from joining. and then there needs to be a massive marshall plan international rebuilding effort that empowers syrians and isn't just a money laundering scheme for corporations to do the rebuilding. on top of that, there needs to be UN peacekeepers with actual backbones during the entire process while syrian civil society rebuilds itself.
so of course this won't happen. instead assad will remain in power, the UN will send aid that will be funneled into a few rich syrians pockets, and the country will remain devastated for generations.
