The Security Dilemma and Ethnic Conflict – Comprehensive Notes
The Security Dilemma and Ethnic Conflict – Comprehensive Notes
The Security Dilemma
Core idea: In the wake of imperial collapse, groups must suddenly provide their own security in anarchy. Each neighboring group asks:
Is the other group a threat?
How large is the threat?
Will the threat grow or diminish over time?
Is there anything that must be done immediately?
The answers shape the likelihood of conflict.
Realist lens: Anarchy (absence of a sovereign) makes security the primary concern of political units. As long as some groups care about survival as independent entities, there will be competition for power and security.
Relative power is often ambiguous and interpreted differently by neighbors. What seems sufficient for one defender may look offensive to another.
Cooperation to mute security competition is hard because perceived cheating can leave one side militarily weakened; fear of betrayal is pervasive.
The security dilemma tends to intensify when two conditions hold (see below). It is especially painful when imperial orders collapse and multi-ethnic groups must build new security arrangements.
Conditions that intensify the security dilemma
Indistinguishability of offence and defence: When neighboring groups have similar military capabilities, they cannot signal defensive intent clearly. Offensive forces can be framed as defensive, and vice versa.
Example: Armour is often viewed as both offensive and defensive; if armour is owned by both sides, signals of defensive posture are unreliable, so actors infer the worst.
Offensive advantage and efficiency of attack: If offensive operations are more effective than defensive ones, states (or groups) may choose to strike first to survive. This can foster preventive war if a temporary advantage appears.
Consequences: When offence has the advantage, even a modest numerically superior group may perceive a dramatic increase in success probability, incentivizing preemptive strikes during crises.
The Indistinguishability of Offence and Defence
Newly independent groups must assess whether neighbors pose a threat by examining military capabilities, cohesion, and past performance.
Military technology and organization are often cited as the main determinants of the offence–defence distinction, but actual history shows this distinction is frequently blurred, especially in land warfare.
Even states with defensive-looking force structures (e.g., infantry-focused militaries) can have strong offensive potential if there is high cohesion and motivation.
Historical patterns: The strong group identity of a sponsor (ethnic, religious, cultural) can itself become a source of offensive capability, because cohesive groups mobilize effectively for aggression when facing threats.
How groups assess others’ threat potential:
They rely on historical records of behavior when other regimes were unconstrained.
The collapse of empires often produces poor, politicized, or oral-history-based narratives, which exaggerate threat perceptions.
Politicized histories and propaganda can magnify perceived threats and trigger armament spirals.
Consequence: Cohesion and group solidarity become central to perceived capability, sometimes more influential than material assets.
The Superiority of Offensive over Defensive Action
Two broad factors influence the dominance of the offensive:
Technology generally affects all participants, but its impact varies by context. Nuclear weapons are a major exception where group cohesion matters less for deterrence.
Geography: When empires collapse, political geography can create an offence-dominant world, especially for groups surrounding others or forming enclaves (islands) within larger populations.
Nuclear weapons: If a group inherits a nuclear deterrent and neighbors do too, the security dilemma is dampened because counterforce or massive retaliation options blur the offensive–defensive distinction.
Geography and strategic considerations:
Surrounding or encircling positions can force some groups to adopt offensive strategies to break encirclement.
Islands of population (irredentism) within hostile or mixed territory can sound alarm bells for rapid offensive action to secure vulnerable enclaves.
Islands may differ in defensibility; some are easily blockaded or attacked, others have potential allies or geographic features that can deter aggression.
Inter-territorial disputes and ethnic cleansing:
The tactical advantage of offensive actions against unarmed civilians can be substantial, especially when populations are divided within a contested territory.
Small bands or fanatics can trigger disproportionate political responses and magnify initial fears.
The role of international organizations:
The UN has often failed to anticipate or credibly guarantee peace; it tends to broker cease-fires rather than durable settlements, which can protect gains of the winning side and inadvertently sustain offensive momentum.
Windows of Vulnerability and Opportunity
When central authority collapses, groups must estimate power relative to others and decide whether to act now or wait.
Several factors shape preventive war incentives:
Relative strength and state-formation pace: Uneven post-empire remnants create early-mover advantages for some groups. If stronger groups expect advantages to wane, they may act to lock in gains.
Distribution of military assets and resources (conscripts, weapon stocks, industrial capacity, currency reserves) is uneven after empire collapse and can tempt preventive grabs.
Expectations of outside intervention and alliances complicate calculations; misperceptions about allies can lead to miscalculation.
External shocks: The post–Cold War era generated many crises that could trigger opportunistic actions as great powers are preoccupied with other problems.
Arms and resource stakes:
Armament caches become strategically valuable due to scarcity and the lure of quick increases in relative power.
Conscription under the old regime boosts the ease of arm supply theft and integration into new forces.
External actors and deterrence:
The credibility and presence of external guarantees can affect leaders’ willingness to pursue preventive aggression.
Large crises and media access can accelerate decision cycles and pressure decision-makers to act quickly.
Croats and Serbs (Yugoslavia case)
Core factors shaping the Yugoslav dissolution through the security-dilemma lens:
Re-emerging identities were read as offensive threats because of past brutal episodes (World War II atrocities); both sides feared domination by the other.
Offensive advantage appeared, particularly against Serbs marooned in Croatian and Muslim areas; power asymmetries existed among republics.
Not all republics were equally powerful; power assets varied by population, economic resources, and access to assets from the old regime.
Small violent groups and nationalist histories (e.g., Ustashe and Chetniks) shaped the security environment.
History and narrative dynamics:
Croats and Serbs have a long warlike historical memory, feeding fear and mistrust.
The Yugoslav federation built on centralized power Posen notes, but with local autonomy pressures, political leaderships argued about autonomy vs centralization.
Specific triggers and signals before the conflict:
Between 1987–1990: Slobodan Milosevic ended Kosovo and Vojvodina autonomy; Croatian Dalmatia referendum (August 1990) showed Serb resistance in Croatia; heavy weapons were impounded by the Yugoslav army (October 1990), widening Serb advantage.
By 1990–1991: Croatian leadership moved toward independence; Serbia anticipated a potential attack and accelerated preparations; Croatian secession was partly catalyzed by fears of Serbian domination.
Key numbers and context:
Serbs in Croatia were scattered as vulnerable islands; they could be rescued only by offensive action from Serbia, complicated by Bosnia's status.
Serbia’s initial military leverage was significant due to weapon stocks, access to the old regime’s assets, and external allies; but Croatia’s growing international recognition and allied support suggested a future growth in Croatian military power.
The balance of power favored Serbia early on, but did not guarantee long-term dominance as Croatia’s power and alliances grew.
Signals of intent and perceptions of threat:
Milosevic’s policies (e.g., ending autonomy, referendums) suggested malign intent from the Serbian side.
Croatia’s leadership feared suppression or arrest if it did not act quickly to secede.
Outcomes and implications:
The security dilemma helped explain why preventive war incentives were high for Serbs and why local bands and nationalist mobilization accelerated conflict.
External misperceptions about Germany’s role and influence in the region affected calculations about external support and intervention.
Russia and Ukraine (post-Soviet relations)
Why the Yugoslav pattern is not replicated here (at least initially):
Perceptions of identity cohesion are less threatening; nuclear deterrence remains a stabilizing factor for both sides.
Settlement patterns and geographic proximity are different from the Croats–Serbs context; and there is a distinct nuclear dimension.
Nuclear deterrence and its effects:
The former Soviet nuclear arsenal in Ukraine (and Russian forces in Russia) creates a strong deterrent against major escalations.
Ukraine’s nuclear stocks on Ukrainian soil complicate Russian military plans and incentivize restraint, since seizure of Ukrainian weapons could escalate to a broader crisis.
Key factors stabilizing the Russia–Ukraine dynamic:
Mutual deterrence prevails due to large nuclear forces on both sides.
Ukraine’s large Russian minority (e.g., Russians in Ukraine) complicates the calculus of ethnic mobilization and intervention.
The proximate military and political histories between Russians and Ukrainians are less violent than those in the former Yugoslavia; relatively fewer nationalist-outbreak patterns have emerged.
The famine episode (1930–32) and nationalist narratives:
The famine becomes a potential tinder for nationalist grievances if Ukrainians blame Russians for the famine; or it can be framed as a historical misdeed by a discredited regime to provoke distrust.
Geopolitical and economic considerations:
About 12 million Russians in Ukraine (roughly 12{,}000{,}000) constitute about 21egin{lflat} au igr percent igr of the population, shaping settlement patterns and political cohesion.
Ukraine’s industrial base and wartime production capacity were significant factors in the post-Soviet power balance; Ukraine produced substantial portions of Soviet industry (e.g., 18 rac{ ext{percent}}{ ext{of population}} and shares like 33 ext{ extpercent} of televisions, 25 ext{ extpercent} of computation equipment, 22 ext{ extpercent} of tractors, 31 ext{ extpercent} of harvesters).
External actors and policy recommendations:
Western diplomacy should encourage even-handedness and avoid patronizing either side; external guarantees should be credible and supported by clear, verifiable commitments.
If Ukraine eliminates nuclear weapons, Ukraine may rely more on nationalism to strengthen its army, which could raise instability; thus, denuclearization should be phased and tied to credible security assurances.
Non-proliferation policy can help stabilize future relations; keeping some nuclear deterrence on Ukrainian soil could deter aggressive actions, but must be credible and verifiable.
Comparison Summary
Yugoslavia vs. Russia–Ukraine:
In Yugoslavia, identity perceived as offensive threat due to weak conventional power and brutal historical memory; windows of opportunity for preventive war were wide, and bands of violence emerged early.
In Russia–Ukraine, nuclear weapons mute conventional competition; if Ukraine denuclearizes, nationalist motivations could grow, potentially increasing risk; Russia’s conventional power advantage is significant, but nuclear deterrence and geographic proximity complicate aggressive action.
External factors and alliance dynamics differ: Western guarantees and German influence played a different role in Yugoslavia, while Western diplomacy toward Ukraine/Russia centers on credible deterrence and political stability.
Indicators of trouble and peace:
If Russia or Ukraine reduces nuclear capabilities, risk of nationalist-driven escalation could rise.
If Ukraine maintains nuclear deterrence, Russia faces a higher threshold for intervention due to potential escalation into a broader nuclear crisis.
Conclusion
Three main conclusions drawn by Posen:
The security dilemma and realism can explain and predict conflict probabilities and intensities among groups emerging from collapsed empires.
The risks associated with these conflicts are high, given how identity, coercion, and history interact with the security-dilemma dynamics.
Outsiders can help reduce the odds of conflict by addressing the fears driving groups’ security calculations and by reducing windows of opportunity; however, the self-help nature of the system makes large-scale external intervention challenging and sometimes ineffective unless credible guarantees and long-term commitments are provided.
Policy-relevant implications:
Encourage groups to discuss and reconcile competing histories to reduce deep-seated fears.
Non-governmental organizations could help mediate historical narratives and promote reconciliation.
External powers could threaten not to act when a state abuses a minority, as a deterrent; but this requires reliable monitoring and enforcement.
Arms transfers to bolster defensive capabilities can be considered, but risks of shifting military balance must be carefully weighed.
Non-proliferation policy matters: keeping some nuclear deterrence in a transitional phase can stabilize the region, but denuclearization should be approached cautiously with credible security guarantees (e.g., START-type arrangements).
Final caution:
It will often be impossible to secure all neighboring groups; wars can occur despite best efforts. Peace efforts must address fears at the root of conflict rather than focusing solely on external guarantees.
