Bob's blog: Controversy erupts over Sgt. Bergdahl

(CBS News) -- As I look back on the release this week of Sgt. Bowe Bergdahl, I have to wonder if the president was fully briefed on the dynamics of this situation before he made a decision. It's hard to believe that he wasn't. But the more you learn about this story, the more you wonder: What was he was getting into when he made this deal?

I don't have an answer to that question, but I still find this story very strange. I want to be very careful; I am not going to criticize somebody who was in captivity as a prisoner. I don't know exactly what the circumstances were of his disappearance and captivity. But the more you find out about Bergdahl, the more questions you have about him.

Another topic on all of our minds is D-Day, which was 70 years ago this week. This pivotal chapter in American history gave us the term "The Greatest Generation." These were people who recognized that the world was on the edge of a new dark age. It would be up to them to make sure that it didn't happen, and they did.

This was my parents' generation. I'm old enough that I can remember World War II. I was just a little boy, but I can remember the soldiers. I can remember rationing. I can remember that where I went to school in Fort Worth, we had to go on two shifts, because people were pouring into town to work at what we called the "Bomber Plant," the factory where they built the B-29s. I can remember all of that.

We hope you will join us this Sunday as we dive into all the week's news. We're going to speak with Sen. Dianne Feinstein, D.-Calif., who leads the Senate Intelligence Committee, as well as Sen. Saxby Chambliss, a ranking member of the committee, about this on Sunday. Feinstein and Chambliss have expressed frustration that Congress was not given notification 30 days before the administration's decision to exchange Guantanamo prisoners for Bergdahl, as is required by law.We'll also talk to journalist David Rohde, who was captured by the Taliban while reporting in Afghanistan in 2008.

Also joining us are Thomas L. Friedman of The New York Times, Peggy Noonan of The Wall Street Journal, David Gergen of Harvard University, and Michael Gerson of The Washington Post.
