Major publications and scholarly contributions

Glennon is the author of books and articles that address separation of powers, executive authority, and international legal constraints on national decision-making. His major monographs critique expansive interpretations of presidential power and analyze the institutional design of American foreign relations.

Views on executive power and national security

Glennon argues for robust congressional oversight and legal constraints on executive action, contending that unchecked presidential authority poses risks to constitutional order and international obligations. He has critiqued doctrines asserted during administrations housed in the White House that expand unilateral executive prerogatives, and has advocated for reinvigorated roles for institutions like the United States Congress, the Federal Courts, and international bodies such as the United Nations and the International Court of Justice. His positions engage with debates over statutes including the War Powers Resolution, authorization measures linked to the Authorization for Use of Military Force, and practices involving National Security Agency surveillance, executive orders, and treaty implementation. Glennon’s analyses have been cited by commentators in forums connected to the Council on Foreign Relations, the American Enterprise Institute, and the Carnegie Endowment for International Peace.
