This week on Babel, Jon talks with Carsten Wieland, a German diplomat who served in the United Nations with three separate special envoys to Syria. They discuss the scale of the humanitarian crisis in Syria, the politicization of humanitarian aid in Syria, and the implications of humanitarian aid policy in Syria for broader international humanitarian law. Then, Natasha Hall, Will Todman, and Danny Sharp continue the discussion about the upcoming vote on cross-border operations in the UN Security Council and its implications.
