(The Hill) – To bring public attention to a criminal practice that continues to harm millions around the world, Congress named Jan. 11 “National Human Trafficking Awareness Day.” The United States leads the world in efforts to end forced labor and modern slavery, devoting resources to protect and assist victims, creating laws to crack down on traffickers, and encouraging other countries to do the same. But there is one place where U.S. government action on trafficking is lagging:  the recruitment and use of children—some as young as 10 years old—as soldiers. In some cases, the United States is possibly even complicit in this crime, by providing military support to governments that it has determined use children as fighters.
