Iraq: 'Like a Bad Relationship'

Available for over a year

With parts of Iraq that US troops once fought to defend now in the hands of Islamist militants, one US soldier who saw combat there tells us what he thinks America’s responsibility is now. We hear what's behind America’s longstanding suspicion of beards, how a tiny wasp from Pakistan might be able to save the US citrus industry and how group prenatal care is becoming more popular across America, leading to healthier babies. Also, we hear why Americans call football soccer and we find out why legendary Top 40 DJ Casey Kasem is also a hero for Arab-Americans. Image: Getty
