Tom Brokaw follows three families through the Iraqi war in his new book

In a "Dateline" exclusive, Tom Brokaw reports The Road Back, a story that follows three families through the war in Iraq. Chronicling their lives from 2002, before the war, until present day, this special edition of "Dateline" premieres Sunday, August 7 at 7pm ET/6pm Central.

More than eight years after the United States invaded Iraq and removed Saddam Hussein, the country is now governed by a democracy of sorts - but Iraq is still a violent place. Nonetheless the United States is still scheduled to remove all of its military forces by the end of this year.

In this "Dateline" special, Brokaw follows an American soldier training to fight in the war; an Iraqi family living under the tyranny of Saddam Hussein and an Iraqi American family who wants to return to Iraq to rebuild their homeland. Their dramatic stories put a human face on colossal historic events.

The Road Back reveals what happened to the families and asks them whether the war was worth it.
