This document is a writing sample from Jae Hwa Shin for an international trafficking course. It is a 25-page research paper about the use of child soldiers in modern warfare and its ethical implications. The summary analyzes the history of child soldiering, noting that traditionally wars were fought by adults, but now over 300,000 children under 18 participate in conflicts. It also outlines the strengthening of international laws around child soldiering over the past few decades, including treaties that prohibit recruitment of those under 15 and define a child as under 18.
