Frame of the discussion

John Mearsheimer presents his theory of conventional deterrence to explain the origins of the war in Ukraine—specifically why Russia attacked on February 24, 2022. He argues this was a case of conventional (non-nuclear) deterrence failure.

Deterrence theory: political vs. military variables

Mearsheimer says deterrence depends on two interacting factors:

  1. Political variable: the intensity/strength of pressures pushing a state toward war—not only whether leaders prefer war, but how “compelled” they feel.
  2. Military variable: battlefield capability, and crucially what strategy the attacker believes it can use successfully.

He emphasizes that war is “politics by other means” (citing Clausewitz).

Three military strategies and their deterrence effects

Mearsheimer argues that attackers in major conventional wars typically consider three options:

  1. Blitzkrieg (quick, decisive victory)

    • If the attacker believes it can achieve this, deterrence is likely to fail.

  2. Attrition (slow, protracted but decisive victory)

    • Deterrence is more likely to succeed, because attrition is costly and difficult.

  3. Limited aim (grab some territory, then shift to defense)

    • Deterrence usually succeeds, since limited wars often evolve into attrition and neither side wants a prolonged conflict.

When limited aim can still fail

He adds that limited aim (and thus deterrence failure) can occur when political pressures are extremely strong, making leaders willing to accept risk even without blitzkrieg capability.

Historical parallels used

  • 1973 Egypt vs. Israel (Sinai): presented as a limited aim operation driven by strong political necessity.
  • 1941 Japan vs. the United States (Pearl Harbor): described as a limited aim attack launched under desperate conditions (economic strangulation; unwillingness to wait) without a realistic path to decisive victory.

Why Mearsheimer rejects the “Russia wanted to conquer all of Ukraine quickly” view

He criticizes the “conventional wisdom” that Russia launched a blitzkrieg to conquer all of Ukraine rapidly. His counter-arguments include:

  1. Russia’s forces were not capable of a decisive conquest

    • He claims Russia had roughly ~100,000 to 190,000 troops (with the subtitles citing General Syrsky’s figure as lower).
    • He argues this was too small and not structured like an offensive-focused army (contrasting it with the Wehrmacht).

  2. Early negotiation behavior is inconsistent with total conquest goals

    • He notes that one day after the invasion (Feb. 25), Dmitry Peskov sought negotiations.
    • He describes the Istanbul negotiations beginning about a month later and claims Russia evacuated around Kyiv, returning control of that region to Ukraine—offered as evidence Russia was not pursuing total conquest.

  3. Core objective: NATO and Ukraine’s neutrality

    • He argues Russia’s main concern was NATO expansion (Ukraine joining/serving as a “Western bulwark”), which he calls an existential threat.
    • Therefore, he says Russia’s goal was to prevent Ukraine from joining NATO, not to fully conquer the country.

His “limited aim strategy” explanation of the war’s origins

Mearsheimer concludes Russia launched a limited aim strategy:

  • entering Ukraine,
  • capturing a small chunk of territory,
  • then moving toward negotiations.

He claims Russia believed negotiations with the West would fail because the West showed “zero interest in negotiating” to prevent war. With no blitzkrieg option and intense political pressure, Russia acted despite the risks.

Why negotiations failed and why the war became attrition

According to Mearsheimer, the Istanbul talks failed, and the conflict turned into a prolonged war of attrition. He argues:

  • Limited aim strategies are problematic because the target state is unlikely to “roll over.”
  • Ukraine, aided by the West (U.S. and European support), kept fighting and believed it could prevail long-term because Russian forces were not strong enough for decisive success.
  • He claims Ukraine (with West encouragement) bore principal responsibility for walking away from Istanbul.
  • Continuing the fight is presented as consistent with his theory’s predicted path from limited aims to attrition.

Bottom-line conclusion

The war is presented as a failure of conventional deterrence driven by:

  • political variables (Russia felt existentially threatened),
  • a military reality (no blitzkrieg capability),
  • and a resulting limited aim strategy that predictably deteriorated into attrition.
