Father of captive U.S. soldier Bowe Bergdahl speaks out on son's potential release

(CBS News) Army Sgt. Bowe Bergdahl's father is weighing in on the potential deal for his son's release from the Afghanistan Taliban, telling CBS News senior correspondent John Miller in an email, "Wars are very easy to get into and very difficult to get out of, especially in South Asia...Diplomacy, diplomacy, diplomacy... it is long overdue in the region."

Miller, who has visited the Bergdahls at their home in Idaho and seen their devotion to fighting for their son's release, said of the father's remarks, "Basically what you're seeing there is a father saying, 'It's time to have this conversation'."

Afghan Taliban offers to swap captive U.S. soldier Bowe Bergdahl for 5 Guantanamo detainees

Then-Pfc. Bowe Bergdahl was taken hostage in June 2009 at the age of 23. In exchange for the now 27-year-old's freedom, the Taliban in Afghanistan wants five members of the Taliban -- currently prisoners at Guantanamo Bay -- to be released from U.S. custody.

This is the second time this has been proposed, Miller, a former FBI assistant director, explained on "CBS This Morning." "The last time it was on the table it was Hamid Karzai and the Afghan government that stopped them and said, 'Wait a minute, there's going to be no deal between the Taliban and the U.S. government. This is about Afghanistan, and we need to be a part of that.' It went off the rails. So it's important to try to get the subject up again."

The five detainees are important to the Taliban who are high-ranking in the military. Miller explained, "On the one hand, getting them back gets them out of Guantanamo, which is one problem and is an important relief to the Taliban. On the other hand, these are not the kind of people you would want to return to the battlefield because the Taliban posture on this is, 'We're ready to talk, and by the way, while we're talking, we'll just keep fighting as we see from the rocket attack the other day at Bagram Air Base.'"

Turning to the potential deal for these prisoners, Miller said the U.S. doesn't want to set a precedent for hostage exchanges but as the drawdown gets closer and closer, he said, "there's a negotiating posture that's very different."

He continued, "At some point you have to have those talks about, 'who do we have that we have to get rid of, who do you have that you're trying to get rid of. How can we make this work for both of us?'"
