In October, the U.S. men's national soccer team advanced to the final stage of qualifying for the World Cup, thanks in part to a half-dozen German-born players fathered by African-American soldiers in the U.S. military.
The choice to play for the U.S. men's national soccer team rather than the German team relates not just to their parents' homelands, but to their racial identities. Soccer player Danny Williams told his parents he felt more American than German.
“When people look at me in Germany, they know that I am not 100% German," Williams says.
