Here are two thoughts I believe need to be held at once: Hamas’s attack on Oct. 7 was heinous, murderous and unforgivable, and that makes it more, not less, important to try to understand what Hamas is, how it sees itself and how it presents itself to Palestinians. Tareq Baconi is the author of “Hamas Contained: The Rise and Pacification of Palestinian Resistance,” one of the best books on Hamas’s rise and recent history. He’s done extensive work interviewing members of Hamas and mapping the organization’s beliefs and structure. In this conversation, we discuss the foundational disagreement between Hamas and the Palestine Liberation Organization, why Hamas fought the Oslo peace process, the “violent equilibrium” between Hamas and the Israeli right wing, what Hamas’s 2017 charter reveals about its political goals, why the right of return is sacred for many Palestinians (and what it means in practice), how the leadership vacuum is a “core question” for Palestinians, why democratic elections for Palestinians are the first step toward continuing negotiations in the future and more.
