The latest Pickens Podcast features one of the most dedicated public servants of the past 40 years: Former Secretary of Defense Bob Gates.

Secretary Gates was Director of Central Intelligence under President George W. Bush, then Defense Secretary under both George W. Bush and Barack Obama.

He is a recipient of the Presidential Medal of Freedom and the Washington Post said he is “widely considered the best defense secretary of the post-World War II era.”

My conversation with him covers national security generally, and focuses on what it means to global oil to have the Russians setting up shop in the Middle East.
