State, Sub-State level Theories and Individual Theories

State-Level of Analysis

  • Focuses on domestic characteristics of states as causes of war.
  • It is a middle ground between system-level (anarchy, power politics) and individual-level (leaders’ psychology).

Regime Type – Democratic Peace Theory

  • Democracies rarely fight other democracies.
  • Institutional constraints: checks & balances, free press.
  • Normative explanation: shared values and peaceful conflict resolution.
  • Critics: Democracies may still fight non-democracies (e.g., U.S. in Iraq).

Expected Utility Theory

  • States go to war if the expected benefits outweigh the expected costs.
  • Leaders assess:
    • Probability of winning.
    • Strategic gains (land, resources, prestige).
    • Political risks of action vs. inaction.
  • War = rational choice under uncertainty.
  • Problem: Misperceptions or false optimism can lead to miscalculation.

Aggressive States

  • Some states have aggressive ideologies or militarized doctrines.
  • Characteristics:
    • High military spending.
    • Expansionist rhetoric.
    • History of using force.
  • Example: Nazi Germany under Hitler.
  • Realist view: Aggressive states must be contained.

Imperialist States

  • War driven by the need for resources, markets, or strategic territory.
  • Often justified by ideology: civilizing mission, manifest destiny, etc.
  • Lenin: Imperialism = “highest stage of capitalism”.
  • Modern forms: Military bases, economic dominance (neoimperialism).

Nationalism

  • National pride → increased public support for war.
  • Extreme nationalism: glorifies the nation, demonizes the “other”.
  • Can escalate ethnic tensions and irredentist conflicts.
  • Example: Israel–Palestine Conflict; Russia and Crimea; India- Pakistan.
  • Can unify states—but also justify aggression.

War as a Diversion (Diversionary War Theory)

  • Leaders may start wars to distract from domestic problems.
  • Rally-around-the-flag effect: boosts popularity in the short term.
  • Especially likely in:
    • Unpopular regimes.
    • Times of scandal, recession, or civil unrest.
  • Example: Russia’s Invasion of Ukraine. Russia faced economic stagnation, anti-corruption protests, and declining popularity of Putin pre-2022.

Individual-level of analysis

What Is the Individual-Level of Analysis?

  • Focuses on the role of human nature, decision-makers, and psychological factors.
  • Assumes individuals, not just states, are central actors in international conflict.
  • Complements system-level and state-level explanations.

Human Aggression and Innate Behavior

  • War may stem from biological drives (e.g., competition, fear, dominance).
  • Theories:
    • Evolutionary psychology: aggression is adaptive for survival.
    • Freudian theory: war as a release of the death instinct (Thanatos).
  • Critics: Cultural and institutional factors often override instinct.
  • Example: Soldiers trained to suppress aggression, yet war still happens.

The Role of Individual Leaders

  • Leaders’ decisions, personalities, and ideologies can trigger war.
  • Traits that increase war risk:
    • Authoritarianism, paranoia, need for power, risk tolerance.
  • Historical examples:
    • Adolf Hitler – aggressive expansionism.
    • George W. Bush – decision to invade Iraq based on personal convictions.
    • Vladimir Putin – personal nationalism and historical revisionism.

Misperception and Miscalculation

  • Leaders often act on incorrect information or cognitive biases.
  • Common misperceptions:
    • Underestimating an adversary’s resolve.
    • Overestimating chances of quick victory.
    • Mirror imaging (assuming opponent thinks like you).
  • Example: U.S. in Vietnam, Russia in Ukraine.

The Fog of War (Uncertainty & Complexity)

  • Term from Carl von Clausewitz: war is shaped by confusion, chaos, and the unknown.
  • In real conflict:
    • Incomplete intelligence.
    • Changing battlefield realities.
    • Emotion-driven decisions under pressure.
  • Leads to unintended escalation and failure to de-escalate.

Case study

  • Individual Factor: Vladimir Putin
    • Aggressive leadership rooted in nationalism and historical revisionism.
    • Misperceptions: Overestimated Russian military strength and Ukrainian resistance.
    • Fog of War: Poor battlefield intelligence and miscommunication led to strategic failures.
    • Some analysts argue Putin’s personalist rule and isolation made him more prone to risky decisions.
