In terms of poetry, he is best known for his book-length poem Coming to Jakarta (subtitled "a poem about terror"), which describes in measured, prosodically regular verse the 1965 crisis in Indonesia that resulted in the Indonesian Civil War and the deaths of as many as half a million people, in which he believed the CIA to have played a role.
Scott is far from a stridently political poet, working always to connect the polemical to the personal. In Coming to Jakarta he writes:
To have learnt from terror
to see oneself
as part of the enemy
can be a reassurance
In the context of this emotional and psychological side of conflict, Scott alternates between descriptions of his own life—"dressed up in polished / gaiters with a buttonhook"—and the massive violence of his principal subject. Somewhere between confessional and scholarly, his poems often contain citations in the margins.
Scott has described his poem Minding the Darkness as his most important, though he concedes that "Like other long poems by older men. . . it toys dangerously with abstract didactic principles." The poem is intended as the culmination of a major poetic project of which Coming to Jakarta was the inception.
Scott has written about the role of the "deep state" (as opposed to the "public state"). Rejecting the label of "conspiracy theory", he has used the phrase "deep politics" to describe his political concerns. His interest in contemporary history has spilled over into his works of poetry, some of which must contain marginal notes to explain to readers which documents or real-world news events are being referred to. His book, The Road to 9/11 (2007), deals with geopolitical context of events leading to 9/11, and argues "how U.S. foreign policy since the 1960s has led to partial or total cover-ups of past domestic criminal acts, including, perhaps, the catastrophe of 9/11." His books The Road to 9/11 and American War Machine are available in French under the titles La Route vers le Nouveau Désordre Mondial and La Machine de Guerre Américaine. The latter was reviewed in March 2011 by Bernard Norlain, a retired French five-starGeneral of the Air Force. In all, his books have been translated into French, German, Italian, Spanish, Russian, and Bahasa Indonesia. His articles have been translated into 16 languages, including Turkish, Arabic, Persian, Chinese, and Japanese.
Of Scott's book, American War Machine: Deep Politics, the CIA Global Drug Connection, and the Road to Afghanistan (2010), Daniel Ellsberg commented: "I said of Scott's last brilliant take on this subject, Drugs, Oil and War, that 'It makes most academic and journalistic explanations of our past and current interventions read like government propaganda written for children.' Now Scott has written an even better book. Read it!"
An aspect of Scott's work that combines both his investigating interests and his poetry is illustrated by The Global Drug Meta-Group: Drugs, Managed Violence, and the Russian 9/11.
In 1972, Bobbs-Merrill Company published Scott's The War Conspiracy. The book describes Scott's theories of why the United States went to war in Vietnam.Kirkus Reviews said War Conspiracy is "undoubtedly one of the most important overviews to date of the subterranean reaches of the U.S. intelligence machine in Southeast Asia."
Kirkus Reviews called the book a "[s]taggeringly well-researched and intelligent overview not only of the JFK assassination but also of the rise of forces undermining American democracy". The Kirkus review also described as a "kind of Rosetta stone for cracking open the deepest darkness in American politics."Publishers Weekly said that Scott's "thoughtful, extremely (and sometimes excessively) detailed book promises more than it actually delivers" and that "the 'facts' on which he relies are often the result of other people's not necessarily accurate reporting". According to PW, "[t]he book's most useful feature is a careful discussion of how U.S. Vietnam policy changed abruptly after Kennedy's death."
In a 2004 review for The Wilson Quarterly, Max Holland wrote that "Deep Politics is an unreadable compendium of 'may haves' and 'might haves,' non-sequiturs, and McCarthy-style innuendo, with enough documentation to satisfy any paranoid." Shortly thereafter, Holland reiterated similar comments in a second piece written for Reviews in American History and criticized the University of California Press' editorial committee for approving the publication of the book: "This peer approval by a major university press illustrates the boundless and utter disbelief in the Warren Report that exists even in the highest reaches of the academy, and it also reveals the gross inattention given to the subject by serious historians." Scott responded with a letter to the editor stating: "I was disappointed to see those who have published me attacked vigorously for doing so by a major historical journal. I continue to believe that it is the job of the academy to open minds, not to close them."
In 2013, the founder of Salon news website, David Talbot, included Deep Politics in his list of top seven "best books on the subject", describing the work as a "masterpiece, a meticulously detailed examination of the deep network of power that underlies the events in Dallas.... filled with provocative insights about how the upper circles of U.S. power actually operate."
