War and armed conflict shape global security dynamics. This section examines the causes, from realist power struggles to liberal cooperation theories. It explores how domestic factors like nationalism and resource scarcity contribute to conflicts.

International dynamics play a crucial role in triggering wars. Territorial disputes, misperceptions, and security dilemmas can escalate tensions between nations. Understanding these factors is key to preventing and resolving armed conflicts in the modern world.

Theoretical Perspectives

Realist and Liberal Approaches to War

• Realism emphasizes power, security, and self-interest as primary drivers of state behavior in international relations
  • States operate in an anarchic system without a higher authority
  • Conflict arises from competition for power and resources
  • Military strength and balance of power are crucial for maintaining stability
• Liberalism focuses on cooperation, international institutions, and shared values as means to prevent war
  • Democratic peace theory suggests democracies are less likely to go to war with each other
  • Economic interdependence reduces incentives for conflict
  • International organizations promote peaceful dispute resolution

Social Constructivism and Diversionary War Theory

• Constructivism examines how ideas, norms, and social interactions shape international relations
  • Identities and interests of states are not fixed but socially constructed
  • Shared understandings and cultural factors influence perceptions of threats and enemies
  • Norms of appropriate behavior can evolve to promote peace or justify conflict
• Diversionary war theory posits that leaders may initiate external conflicts to distract from domestic problems
  • Used to boost popularity and national unity during times of internal crisis
  • Can backfire if the war is unsuccessful or costly (Falklands War)
  • May be employed by both democratic and authoritarian regimes

Domestic Factors

Nationalism and Ethnic Conflict

• Nationalism involves strong identification with one's nation and support for its interests
  • Can foster unity and patriotism but also lead to xenophobia and aggression
  • Often used by leaders to mobilize popular support for war (World War I)
  • Irredentism seeks to incorporate territories with co-ethnic populations into the nation-state
• Ethnic conflict arises from tensions between different ethnic groups within a country
  • Can result from historical grievances, discrimination, or competition for resources
  • May lead to civil wars or involve intervention by external powers (Yugoslav Wars)
  • Often exacerbated by political manipulation of ethnic identities

Resource Scarcity and Power Vacuums

• Resource scarcity can trigger conflicts over access to vital resources
  • Competition for water, arable land, or energy sources (oil) may lead to interstate wars
  • Climate change exacerbates resource scarcity and increases potential for conflict
  • Resource curse theory links abundance of natural resources to increased likelihood of civil wars
• Power vacuums occur when there is a lack of effective governance or authority
  • Can result from state collapse, regime change, or withdrawal of a dominant power
  • Often lead to internal conflicts as various factions compete for control
  • May invite intervention by external powers seeking to expand their influence (Syrian Civil War)

International Dynamics

Territorial Disputes and Misperceptions

• Territorial disputes involve disagreements over the control or ownership of land
  • Can arise from historical claims, strategic interests, or resource competition
  • Often tied to national identity and difficult to resolve (Kashmir conflict)
  • May escalate into armed conflict if diplomatic efforts fail
• Misperception in international relations can lead to unintended conflicts
  • Involves misunderstanding the intentions, capabilities, or resolve of other states
  • Can result from cultural differences, inadequate intelligence, or cognitive biases
  • May cause overreaction to perceived threats or underestimation of risks (Cuban Missile Crisis)

Security Dilemmas and Preemptive War

• Security dilemma occurs when actions taken by a state to increase its security are perceived as threatening by others
  • Leads to a spiral of mutual distrust and arms buildup
  • Can result in conflict even when neither side initially intended it
  • Difficult to escape due to uncertainty about others' intentions (Cold War arms race)
• Preemptive war involves striking first to prevent an anticipated attack
  • Based on the belief that war is inevitable and striking first offers strategic advantage
  • Can be justified as self-defense but risks escalating tensions
  • May be based on faulty intelligence or misperceptions (Iraq War 2003)
