In his first book, "Deadly Logic: The Theory of Nuclear Deterrence" (1966), Green criticized the allegedly scientific approach to the nuclear arms race advanced by strategic policy scholars and policymakers of the time. Their reliance on scientific solutions to nuclear escalation was, he argued, profoundly unscientific and inattentive to the deeper moral and political dimensions of the possibility of nuclear warfare. In a further development of that criticism in "Science, Government, and the Case of Rand: A Singular Pluralism" ("World Politics" 1968, reprinted in "American Democracy", ch. 2), he pointed out that the story of the Rand Corporation’s relationship to the theorists of nuclear deterrence gave lie to the conventional liberal pluralist notion that policy-setting in the U.S. was open to all would-be participants on an equal basis. The book and the essay were among the seminal critiques of liberal pluralism being developed out of the social and professional ferment of the 1960s. That essay was shortly followed by "I Have a Philosophy, You Have an Ideology: Is Social Criticism Possible?" ("Massachusetts Review", 1971, reprinted in "American Democracy", ch. 1), which argued that an appropriate respect for facts and reason distinguishes genuine philosophical or empirical argument from the illusions of ideological thinking.
