- Peter Bergen: Gen. Jim "Mad Dog" Mattis is a consummate reader, with an extensive collection of books
- Clues into how he will run the Pentagon can be found in them and his own published works, he writes
Peter Bergen is CNN's national security analyst, a vice president at New America and a professor of practice at Arizona State University. He is the author of "United States of Jihad: Investigating America's Homegrown Terrorists."
(CNN)In picking Gen. Jim Mattis for Defense secretary, President-elect Donald Trump has said that he found his "Gen. George Patton." Yet that label may not really capture what makes Mattis a distinctive choice. Mattis has been sharply critical of President Barack Obama's policies on Iran, and Obama's capping of troop numbers and campaign end-dates in theaters of war such as Afghanistan and Iraq. Mattis also appears to be a skeptic of the Obama-era policy of putting women into combat roles.
