Of the exchange for Sgt. Bergdahl, Mr. McChrystal said: "It's hard to make a judgment on a deal like that. It's an American soldier, and so getting him back to me is a pretty sacred responsibility."
"The five that are back — presumably, they will go back to the battlefield, but they won't change the dynamics," Mr. McChrystal said Sunday on CNN's "State of the Union." "It's not going to change the balance of effort there, five guys, but it's just something we are — watch as we go forward."
