Humanitarian intervention His doctoral thesis as a
Rhodes Scholar, became one of his first books,
Just War or Just Peace? Humanitarian Intervention and International Law. Before publication as a book, the work had originally won a 2000
Dasturzada Dr Jal Pavry Memorial Prize for "best thesis in international relations". One review article of this book by Nico Krisch in the
European Journal of International Law described Chesterman's book as being pessimistic about
humanitarian intervention, when compared to his contemporary
Nicholas J. Wheeler who is more optimistic about establishing an international framework for "ideal humanitarian intervention". Chesterman does not believe that "ideal humanitarian intervention" exists; according to Krisch, he instead belongs to the school of thought that argues that states should "justify their action based on political arguments" rather than relying on a "[humanitarian] recognition of exception to the use of force". Though the intervention would go against international law, it would be in Chesterman's words, a "venial sin". As Krisch analyses, Wheeler also raises "plausible" opposition to this – it would create a "perception" that "powerful states" could ignore international law whenever they wished, pushing other countries to treat international law "equally cavalierly". Noting Chesterman's position, Krisch writes, "law loses much of its weight if its deviation from moral standards is openly admitted and other ways of justification are recognised." Chesterman further argues in
Just War or Just Peace that the enforcement of the
Iraqi no-fly zones and the
Operation Deny Flight (the
no-fly zone in Kosovo) went outside the framework of the United Nations, but Krisch calls this claim "overstated". Nevertheless, the book received an
American Society of International Law Certificate of Merit. In
Just War or Just Peace, Chesterman rejects the idea that the
Federal Republic of Yugoslavia (FRY)'s repression of the Kosovars represented a "supreme humanitarian emergency". Instead, as Nicholas Wheeler notes, Chesterman is "sympathetic" to Russia's historical argument before the Security Council (SC) "that the crisis did not merit an armed response". Going against the widely accepted view is that Russia's threat to use its
UN Security Council veto against UN intervention in Kosovo was an act of "mere contrariness" to NATO, Chesterman instead argues NATO "never seriously contemplated that there might be genuine objections to the policies of NATO member states in their dealings with [the FRY]." Chesterman and his allies, Wheeler writes, would actually believe that Russia's official SC position matched its actual belief on the matter; to Chesterman, Russia would have changed its position had the situation "worsened along the apocalyptic lines predicted by NATO governments". Nevertheless, writing in the journal
International Affairs, Wheeler concluded that "Chesterman has written a
tour de force that exposes the weaknesses of the arguments supporting a doctrine of unilateral humanitarian intervention in international society ... Chesterman rejects the claim that states have a legal right to act as vigilantes in support of Council resolutions, even if they believe that this is the only means to stop a genocide. The powerfully argued thesis of this scholarly work is that accepting this proposition in law is 'a recipe for bad policy, bad law, and a bad international order'." As a
Modern Law Review article noted, Chesterman condemned
NATO's intervention in the
Kosovo War as being "completely outside the United Nations system of security and a threat to
global stability". He later drew parallels between Kosovo and the arguments raised by Russia for its 2014 annexation of Crimea.
State-building Chesterman's book
You, The People: The United Nations, Transitional Administration, and State-Building (Oxford University Press, 2004), studies the foundation of new institutions in war-torn regions such as the former Yugoslavia and southeast Asia. Noting Chesterman's intent to highlight the mutually related yet sometimes mutually opposing "ends of liberal democracy and the means of benevolent autocracy," a review article in the
George Washington International Law Review called it a "misdelivered message". It was reviewed positively in the
New York Review of Books by
Brian Urquhart who wrote that "the weight of the subject and the depth of the research are supported by wit, candor, brevity, and analytical writing of a very high order." Another review in
Human Rights Quarterly stated that the book "speaks with the authority of a major global commission study and offers analyses and prescriptions with important implications for human rights scholars and practitioners."
Intelligence agencies Chesterman has written on the regulation and oversight of
intelligence services, including a monograph published by Australia's
Lowy Institute for International Policy in 2016. In an opinion piece published in the global edition of
The New York Times in November 2009, he argued for limits to the outsourcing of intelligence activities to private contractors such as
Blackwater.
Oxford University Press published Chesterman's twelfth book in March 2011. Entitled
One Nation Under Surveillance: A New Social Contract to Defend Freedom Without Sacrificing Liberty, it examines what limits – if any – should be placed on a government's efforts to spy on its citizens in the name of national security. Writing in the
New York Review of Books,
David D. Cole said that Chesterman "argues convincingly that the specter of catastrophic terrorist attacks creates extraordinary pressure for intrusive monitoring; that technological advances have made the collection and analysis of vast amounts of previously private information entirely feasible; and that in a culture transformed by social media, in which citizens are increasingly willing to broadcast their innermost thoughts and acts, privacy may already be as outmoded as chivalry."
Data protection and artificial intelligence 2026 In January 2014, Chesterman published an edited volume entitled
Data Protection Law in Singapore: Privacy and Sovereignty in an Interconnected World (Singapore: Academy Publishing, 2014). He is also the author of
We, the Robots? Regulating Artificial Intelligence and the Limits of the Law (Cambridge: Cambridge University Press, 2021).
Reports on 15 February 2012 Chesterman has been author or co-author of various reports for the United Nations, governments, and private bodies. Examples include: • "The UN Security Council and the Rule of Law", arguing for greater accountability and circulated as a document of the United Nations in all UN languages; • "Assessment of Implementation of Articles 3 and 4 of the Ethical Guidelines for the Government Pension Fund – Global", reviewing the ethical investment strategy of Norway's
sovereign wealth fund and co-authored with the
Albright Group founded by former U.S. Secretary of State
Madeleine Albright; • "Asia's Role in Global Governance", a report of the
World Economic Forum's Global Redesign Initiative co-authored with
Kishore Mahbubani.
Other books Other publications have focused on the
United Nations, particularly the role of its
Secretary-General, and the rise and regulation of private military and security companies. ==Personal life==
