Lecture Notes: Regions and Powers - The Structure of International Security

Introduction

  • Discussion of the book "Regions and Powers: The Structure of International Security" by Barry Buzan and Ole Waever.
  • Main argument: Regional Security Complex Theory (RSCT) is used to evaluate the balance of power between regionalizing and globalizing trends.

Regional Security Complex Theory (RSCT)

  • Distinguishes between system-level (global powers) and subsystem-level (lesser powers) security interdependence.
  • Regional threats travel easier over short distances, creating regionally based clusters (security complexes).
  • Most states are primarily concerned with neighboring capabilities and intentions.
  • Theory combines materialist and constructivist approaches.

Historical Stages of Regional Security

  1. Modern Era (1500-1945):
    • Dominance of the European international system became global.
    • European powers stifled indigenous regional security dynamics.
  2. Cold War and Decolonization (1945-1989):
    • Decolonization created new states and regional dynamics.
    • Bipolar rivalry (USA vs. Soviet Union) affected regional security.
  3. Post-Cold War Period:
    • End of Cold War changed superpower influence and increased non-military security issues.

Global Powers and Security Levels

  • Superpowers:
    • Require global military and political reach (19th century: Britain, France, Russia; Post-WWI: Britain, USA, Soviet Union; Post-WWII: USA, Soviet Union; Post-Cold War: USA).
  • Great Powers:
    • Less demanding in capability and behavior than superpowers.
    • Treated based on system-level calculations of power potential.
  • Regional Powers:
    • Define the polarity of regional security complexes.

Regional Security Complex Theory Main Variables

  • Penetration:
    • Global powers form security alignments with regional states, linking local and global security dynamics.
  • Security Complex Structure:
    • Defined by boundary, anarchic structure, polarity, and patterns of enmity/amity.
  • Possible Evolutions:
    • Maintenance of status quo, internal transformation, external transformation.

Types of Regional Security Complexes

  1. Standard: Polarity determined by regional powers.
  2. Centered on Superpower/Great Power/Regional Power/Institution.
  3. Supercomplexes: Strong inter-regional level of security dynamics.

Unstructured Security Regions

  • Occur due to low local state capabilities or geographical isolation.
  • Overlay: Great power interests dominate local security relations (e.g., European colonization, Cold War Europe).

Conclusion

  • Interwar Period: 3+3 global power structure (Britain, USA, Soviet Union; Germany, Japan, France).
  • Cold War: 2+3 global power structure (USA, Soviet Union; China, Japan, Western Europe).
  • Post-Cold War: 1+4 global power structure (USA; China, EU, Japan, Russia).
    • Increase in regional security complexes (11 by 2001).
    • Future scenarios: 2+x or 0+x global power structures.

Final Remarks

  • Number of superpowers is shrinking.
  • Regional security complexes rose sharply mid-20th century, stabilizing afterward.
