Strategic assessments reveal a given nation’s understanding of the security landscape and its relative power position. However, strategic appraisals can also betray the fundamental values and prevailing attitudes of the country generating the assessment. American estimators have shown a propensity to frame questions in a manner reflecting their internal predispositions—a tendency that has often contributed to flawed images of external threats. This was the case during the early Cold War when American analysts routinely transferred judgment to Soviet decision-makers. By projecting their own proclivities onto an adversary whose preferences did not align with the United States, analysts persistently misdiagnosed the threat and concealed opportunities to exploit Soviet vulnerabilities. It was not until American strategic analysis underwent a dramatic transformation in the 1970s that more reliable assessments began to emerge. The Cold War, then, offers a stark warning about the pitfalls of an ethnocentric view of the security landscape. Adversaries, after all, are bounded by distinctive national styles that diverge from American logic.
