Walter Russell Mead, over on the American Interest website, has a sobering article: Misery is Humanitarian's Gift to Aleppo. It is simply another example of the old saying that "the road to Hell is paved with good intentions". We Americans talk a lot about improving the world and bringing help and democracy to others, but when push comes to shove we too often make promises we can't keep, or worse yet, promises we don't keep, raising hopes (and sometimes even revolutions) and then dashing them. Syria is a classic current example.
Worth thinking about.
