Mattis Gives His Take On Top National Security Threats Facing U.S.

Former Defense Secretary Jim Mattis said on Sunday that increasing political division in the United States and the growing national debt are the two largest internal threats to U.S. national security.

Mattis made the remarks while appearing on CBS News’ “Face The Nation” with host Margaret Brennan, who said that Mattis wrote in his new book that “Pakistan is the most dangerous country in the world.”
