Jake Sullivan, the president’s national security adviser, needs only the briefest of introductions. As his title implies, Jake is the primary adviser to Joe Biden on all matters of national security. He also runs the National Security Council, which provides guidance to the president, and directs the interagency process—that is, he coordinates between the various government departments that play a role in national security, like the departments of State, Defense, Energy, and Treasury, the Joint Chiefs, and Office of the Director of National Intelligence.
I’ve known Jake since he was Hillary Clinton’s right-hand man at the State Department and, later, the chief foreign policy adviser on her presidential campaign. Alas, the White House job would have to wait. While the Democrats wandered in the wilderness during the Trump years, Jake teamed up with former Obama adviser Ben Rhodes to form National Security Action, an advocacy group focused on counteracting (and counter-messaging) the occasionally insane foreign policy of the new president—who, as you’ll recall, wanted to purchase Greenland. The group was also a kind of administration in waiting, a who’s who of Democratic foreign policy hands including Wendy Sherman, Tony Blinken, Ned Price, Susan Rice, and Samantha Power—all of whom got senior jobs under Biden.
