Have we learned anything from the Cold War?

At a time when the U.S. is fighting wars on two fronts, the recent publication of "The Hawk and the Dove – Paul Nitze, George Kennan, And the History Of the Cold War" has reminded the world how important the lessons of history can be. What policies are more effective: aggression or reconciliation? That's how Nicholas Thompson makes a work of two contrasting biographies relevant and important to us today.

Nicholas Thompson: tech guru, recording artist, and now historian, is the ultimate jack-of-all-trades. His day job is as a senior editor at Wired magazine delving into everything from the existence of a Russian Doomsday machine to the latest developments in smartphones.

Send Nicholas your questions on anything from secret Russian weapons to the inside buzz on the new Mac tablet. We'll put them to him live during Friday's show.
