Former CIA Director Porter Goss sat down with WINK News to talk about the cost of Sgt. Bowe Bergdahl's freedom.

"I think what we have gotten is a soldier back -- thank God for that -- but I don't think the full price is going to come in for the following years, and I think it's going to be a lot heavier than anybody knows," Goss said.

Goss said the exchange of five Taliban prisoners from Guantanamo Bay for U.S. Army Sgt. Bowe Bergdahl sends a dangerous message to America's enemies.

"I think it sends a message that we are now in the hostage exchange business," Goss said.  "Hostage extortion is one of the main tools of the radical fundamentalists.  This will encourage them to do more of that kind of thing, expect us to bargain for it."

Enemies, who, Goss said, are nearly impossible to understand in the western world.

"It's a very hard thing for Americans to understand the culture of these people, and the determination of these people to accomplish their goal," Goss said.  "Because they are willing to give their lives to get the goal. They say, 'We love death more than you love life.'"

Sunday, U.S. Secretary of Defense Chuck Hagel said he stood by his decision.

"Maybe this will be a new opening that can produce an agreement," Hagel said on Meet the Press.

"To think that these people can be talked out of their mission is, to me, foolishness," Goss said.  "It's not going to happen."

As a condition of the release, the newly-freed Taliban fighters must spend the next year in Qatar, where they'll be closely monitored.  Goss said that's not enough.

"These people have blood on their hands. These are not just innocent bystanders. These people were chief of the military in the Taliban.  These people were players and they'll be players again," Goss said.
