Lecture 2: Realism September 6, 2016
Today’s Class • Classical (Human Nature) Realism
• Structural (Neo) Realism – Offensive – Defensive
• MoBvaBonal & Neoclassical Realism – DisBnguishing these from non-realist theories
• Hegemonic Realism (a.k.a. power transiBon theory)
• The Bargaining Model
Classical (Human Nature) Realism
• Cause of conflict is the lust for power rooted in human nature – Animus dominandi, the will for power
• PoliBcs = the compeBBon for power
• Acknowledged that internaBonal system = anarchic, but emphasized individual human nature
• Problem: conflict varies, but human nature doesn’t – Hard to explain variaBon with a constant
Structural (Neo) Realism: Assump-ons
• About the System – System = Anarchic
• About Units – States = main actors – States = like units – States = unitary raBonal actors – States want to survive … – …but are uncertain about others’ intenBons
A Neorealist World
• CompeBBon for power • Self-help • Fear and mistrust • PotenBal for cheaBng makes cooperaBon dangerous
• RelaBve gains concerns further inhibit cooperaBon
• CooperaBon = temporary – No enduring friends, only enduring interests
A Neorealist World, cont.
• Security Dilemma – Increase in your security decreases security of others
• Maximize Security, not power – because states balance, maximizing power triggers SD – Balancing is dominant tendency in the system – States balance against power, don’t bandwagon with it
� Seek an “appropriate” amount of power
• States balance in two ways: – Internal (arms build-ups) – External (alliances)
• Balance = good; imbalance = bad
• Bipolarity > MulBpolarity
Neorealism: Rise of China
• Growth in Chinese capabiliBes induces fears in others – U.S., regional powers
• PotenBal for SD
• Return to bipolarity
• Peace preserved by nuclear weapons, but plenty of compeBBon – a new Cold War
Offensive Realism • Similar starBng assumpBons
– Anarchy – Offensive capability – Uncertainty – Survival – RaBonality
• Predicted behaviors – Fear – Self-help – Maximize rela:ve power
• Hard to determine what an “appropriate” amount of power is
• Best way to survive is to acquire as much power as possible
• Power accumulaBon only stops when states become hegemons – global or regional? – Work to prevent others from becoming regional hegemons
Offensive Realism, cont.
• SD = unavoidable; states have no choice but to compete
• States don’t always balance – opens the door to try to max. rel. power – Want to get others to pay the price of containing rising powers
– Buckpassing common in mulBpolar systems • How powerful the rising power is • Geographic proximity of balancers
Offensive Realism: Rising China
• CompeBBon is unavoidable
• China will pursue regional hegemony
• China will compete intensely with the U.S.
• U.S. will compete to retain its posiBon
• War is not unlikely
Defensive Realism
• Same basic starBng assumpBons, but portrays a less compeBBve world where more cooperaBon is possible – Anarchy – States – Unitary actors – RaBonality – Survival/security-seeking
� Bofom-line: The internaBonal system can drive states into compeBBon and conflict, BUT it doesn’t always
• Puzzle: How does the internaBonal system generate this result?
Defensive Realism: Security Dilemma
• Emphasis on the security dilemma – Policies a state pursues to increase its security can reduce its adversary’s
security – The adversary has the ability to respond in ways that could then reduce
the state’s own security
• SD is logically necessary to generate compeBBon between security seekers
• RaBonal security seekers facing an SD can, under some condiBons, choose compeBBon or war
• BUT, under other condiBons, cooperaBon can be best opBon
The Compe--on Bias in Neorealism • States seek security
• One way to pursue that is to compete – But, compeBng can potenBally reduce your security if the other side reacts – So, compeBBon is not necessarily smart (or raBonal)
• Another way to is make the adversary more secure – If the adversary is more secure, you are more secure!
• Strategy should be designed to reduce the adversary’s insecurity, as well as to deter – The need to strike this balance is another way to understand the SD
• CooperaBon can bring benefits – Arms control to reduce military risks – Restraint to send “costly” signals, reducing poliBcal risks
• Arms control • Unilateral restraint
Varia-on in the Security Dilemma
• The SD can vary in intensity – When SD is mild, internaBonal system does not generate strong
incenBves to compete
• What causes the SD to vary?
• Offense-defense balance – The relaBve ease of afack or defense in war – RelaBve cost of offense vs. defense
• ODB determined by: – Technology – Geography
Offense-Defense Advantage
• Military technology – Mobility favors offense – Firepower favors defense
Offense-Defense Advantage
• Geography – Flat, open terrain favors offense – Obstacles (rivers, mountains, forests) favor defense
Offense-Defense Predic-ons
• Offensive Advantage è SD more intense è War more likely
• Defensive Advantage è SD less intense è War less likely

Offensive or Defensive Advantage
Nuclear Weapons and the SD
• Nuclear weapons favor defense – Deterrence is funcBonal equivalent of defense – Secure retaliatory capability is the key requirement for deterrence
• Nuclear weapons make offense and defense disBnguishable, at least with large arsenals
• Nukes therefore significantly diminish the SD
Defensive Realism and Rising China
• Peaceful rise is possible and intense compeBBon can be avoided
• Nuclear weapons provide core security
• Geography reduces potenBal for invasion – But U.S. could be pulled into conflict in other ways – allies…
• Restraint can be reinforcing – Or compeBBve policies by either side risk damaging poliBcal relaBons
Mo-va-onal Realism: State Type • InternaBonal system = benign, offers few incenBves for aggression
– States balance – ODB typically favors the defense
• Yet aggression someBmes occurs under structural condiBons when it “shouldn’t”
• Offensive realist answer = all states are revisionist!
• MoBvaBonal realist answer = states vary in type – Greedy – Security-seeker/status quo
• State type explains aggression, more than structure
Mo-va-onal Realism: State Type, cont.
• Divides states into greedy states and security- seekers
• Doesn’t try to explain where those moBves come from
• Example: Schweller, Deadly Imbalances – Puzzle: Why do some states bandwagon (ally with the stronger side)?
– Answer: Revisionist states bandwagon, status quo states balance
Mo-va-onal Realism: Informa-on • Recall that SD reflects uncertainty about moBves
• But uncertainty itself is a variable
• High esBmates that the adversary is a security seeker reduce the SD – CooperaBon = less risky
• InformaBon can offset dangerous material condiBons – Power alone does not determine how threatening others are
Mo-va-onal Realism: Variables
• End up with 6 variables – Material variables
• RelaBve power • ODB • O-D disBnguishability
– InformaBon variables • Info about adversary’s moBves • Info about the adversary’s info about your moBves
– State’s moBves • Security seeker vs. greedy
Mo-va-onal Realism: Rise of China
• ImplicaBons of China’s rise depends on China’s type, moBves – Peace is possible if China is security-seeking state – Intense compeBBon and possibly war are much more likely if China is a greedy/expansionist state
• Name of the game is discerning China’s type – Greedy vs. status quo/security seeker – If greedy, limited aims vs. unlimited aims – If limited aims, what does China want?
Non-Realist Theories
• Some theories are called “realist” when they probably aren’t
• Theories that explain raBonal behavior given structural constraints and/or state type = realist
• Theories that explain subopBmal (i.e., non- raBonal) behavior – ojen with resort to theories of domesBc poliBcs – are not realist
Non-Realist Theories: Examples • Jack Snyder, Myths of Empire – Puzzle: Why do some states over-expand when there are no structural incenBves to do so?
– Answer: DomesBc coaliBonal logrolling and naBonalist mythmaking
• “Cult of the offensive” – Puzzle: ObjecBve condiBons in 1914 favored defense, yet states nevertheless adopted offensive strategies
– Answer: European militaries favored offense for organizaBonal reasons + poor civilian control of the military
Hegemonic Realism • Preponderance = peace – System is stable if there is a clear hierarchy of power
• Balance = war – Shij away from preponderance towards equality between the leading two powers foreshadows (hegemonic) war
• “The growth of the power of Athens, and the alarm which this inspired in Sparta, made war inevitable.”
The Case For Hegemony/Unipolarity
• Huge gap in power = no uncertainty
• No power transiBons
• Unipole can intervene to nip potenBal challenges in the bud
• Hard for potenBal opponents to coordinate
• Bids for regional hegemony likely to be opposed by those in the region
Hegemonic Realism: Assump-ons
• Law of uneven growth – States grow at different rates over Bme – Moves them up (and down) the hierarchy of power • In modern Bmes, industrializaBon = key factor
– Triggers conflict between declining hegemon and rising challenger
– Outcome of war re-orders system
Hegemonic Realism: Causal Mechanisms for War
• Disequilibrium in distribuBon of benefits, presBge, territory, etc., in the system – sBll favors the hegemon
• No longer reflects actual balance of power, which increasingly favors the challenger
Hegemonic Realism: Causal Mechanisms for War
• PrevenBve moBve
• Declining power wages war now to prevent challenger from rising and to head off its own decline
• Fight war now to avoid possibility of having to fight a war later under worse circumstances
• Similarity to commitment problem
• Example = Germany vs. Russia, 1914
The Bargaining Model
• Key insight: war is costly – States have to pay a cost for fighBng whether they win, lose, or draw
• Costs of fighBng = big incenBve to negoBate a seflement
• Why not simply skip the fighBng part and go straight to a deal that reflects their relaBve strength? Why does war nevertheless happen?
Ra-onal Explana-on for War #1
• States have private informa-on about their capabiliBes…
• … and incen-ves to misrepresent it
Ra-onal Explana-on for War #2
• States cannot credibly commit to abide by bargains agreed to now if condiBons change in future
Ra-onal Explana-on for War #3
• States cannot reach a bargain because the issue under dispute is indivisible
The Bargaining Model and China • Private informaBon
– China’s moBves – Willingness to fight for territorial expansion – U.S. ability to hit Chinese mobile ICBMs
• Commitment – China’s conBnued rise undermines credibility of any deal struck today
• Indivisibility – “One China” – “Nine dash line” – Status concerns
