With Lebanon's government resigning en masse, it's worth revisiting David Brooks's much-mocked (but then, aren't they all?) column from this weekend, where he identified the question "why not here?" as being the preeminent query in today's world. As he saw it, Ukrainians looked at the peaceful revolution in Georgia and though, hell, we can do that! And they did. And Arabs are looking at the elections in Iraq and, to a lesser extent, Afghanistan, and thinking they should have those too. And so they are.
