General (ret.) H.R. McMaster, the Fouad and Michelle Ajami Senior Fellow at the Hoover Institution, returns to Uncommon Knowledge to discuss his latest book, At War with Ourselves, in which he candidly recounts his experiences as former national security advisor to President Donald Trump from 2017 to 2018.

In this wide-ranging interview, McMaster delves into the complexities and challenges he faced while serving in the administration and describes his role in providing the president with multiple options and safeguarding his independence of judgment, partially by drawing on the Stoic philosophy of Epictetus to “play well the role assigned to you.” He reflects on the internal tensions and conflicts within the White House, often exacerbated by differing agendas among staff and cabinet members. McMaster also discusses the difficulties in maintaining a productive relationship with President Trump, especially when offering candid advice that sometimes led to alienation. The conversation is a revealing look into McMaster's often tumultuous experiences in the Trump White House but also emphasizes the importance of a well-structured decision-making process in the realm of national security.
