Tens of thousands of veterans are suffering from mental illness and homelessness, and as more soldiers return from Iraq those numbers are expected to grow.
"One in three homeless Americans is a veteran. On any given night in this country, an estimated 200,000 are living on the streets. Many served in Vietnam, but experts expect the number of Iraq veterans to swell in coming years. The Army says one in three Iraq veterans will return home with mental health issues. Sooner or later, caring for them will become another cost of war."
