LONDON -- Humanitarian aid rests on the belief that a crisis is a short-term event lasting days, weeks or months, not years. From Syria to Sudan, history says otherwise. Faced with life on the streets, children impacted by a crisis need more than the basics for survival. They need to be able to secure skills for the times ahead. And they need hope. An education -- the prospect of being able to plan and prepare for the future -- is most likely to secure this hope.
