Ep68 “Is It Better to Overestimate or Underestimate Your Enemies?” with H.R. McMaster

Quick Overview

Former National Security Advisor H.R. McMaster argues that it is generally better to overestimate military capabilities and intentions of rivals like China and Russia than to underestimate them, citing historical examples like the Cuban Missile Crisis and Pearl Harbor where underestimation led to disastrous outcomes, while overestimation, though costly, often leads to better preparedness and strategic positioning. McMaster emphasizes that current geopolitical realities, such as China's growing conventional and nuclear power, require policymakers to maintain a high level of vigilance and avoid the illusion of a stable, unipolar world. He concludes that the cost of overestimating is usually less severe than the catastrophic consequences of underestimation, particularly when dealing with actors pursuing revisionist goals.

Key Points: McMaster asserts that overestimating enemies, like Russia and China, is strategically preferable to underestimating them due to the catastrophic costs associated with being surprised by an adversary's true capabilities or intentions. He cites historical failures like the Cuban Missile Crisis and Pearl Harbor as prime examples where underestimation led to near-disaster or actual defeat. McMaster notes that China's military modernization, including its growing nuclear arsenal and advancements in cyber and electronic warfare, demands a sober assessment that avoids wishful thinking about their intentions. He argues that the West, particularly, tends to underestimate authoritarian rivals because of a historical preference for a unipolar world order, which is now being challenged. The cost of overestimation (e.g., spending more on defense) is generally less severe than the cost of underestimation (e.g., being caught unprepared for an attack or coercion). McMaster advocates for intelligence communities to actively challenge their own assumptions and avoid mirroring their adversaries' desired perceptions, referencing intelligence failures like those concerning Saddam Hussein's WMDs. He suggests that even democracies like India are now realizing the need to avoid underestimation as they face increasingly assertive authoritarian neighbors.
