Former Director of National Intelligence James Clapper, whose new book “Facts and Fears” is out now, told me in our interview last week that Russia presents the most urgent national security threat to the U.S., and China the biggest long-term threat.

The big picture: Clapper says Russia is “bent on undermining our system any way they can” and will be as long as Vladimir Putin remains in power, while China's "economic power" and "scientific and technical prowess" present big long-term challenges.
