Summary

In this lecture, Stéphane Taillat, a contemporary history professor, challenges the common narrative of a ‘return of war’ in the 21st century. He distinguishes between ‘war’ as a social institution and ‘use of force’ as a strategic tool. Using data from the Uppsala Conflict Data Program, he shows that while the number of armed conflicts is at an all-time high (61 in 2024), only four are interstate wars, making such wars a statistical anomaly. He argues that war as an institution is becoming obsolete due to international norms (UN Charter), nuclear deterrence, and societal changes like the externalization of war costs. However, the use of force remains common, with states increasingly ‘disinhibited’ in using military power for various objectives, as seen in recent actions by Russia, Azerbaijan, and Rwanda. He attributes this to a triple political, social, and cultural phenomenon, including the decline of US unipolarity and the rise of power politics.

Critical Evaluation

Value of the Information & Strength of the Argument

The lecture provides valuable insights by reframing the debate on war and force. It offers a nuanced argument supported by empirical data (UCDP) and historical examples. The distinction between war and use of force is analytically powerful. The argumentation is coherent and well-structured, though it relies heavily on the speaker’s interpretation and selected examples. The discussion of ‘disinhibition’ and ‘power politics’ is thought-provoking, but the causal links could be more rigorously established.

Scientific Rigor, Source Quality, Title Accuracy

The speaker demonstrates scientific rigor by referencing the UCDP database and French strategic documents. However, the lecture is an opinion piece rather than a systematic review, and some claims lack direct citations. The title accurately reflects the content. The speaker’s academic credentials enhance credibility. No comments were provided for analysis.

Dissenting Sources

  • Human Security Report — Some scholars argue that the decline in interstate wars is not solely due to norms but also to other factors like economic interdependence and the rise of non-state conflicts.

Contribution & Novelties

The lecture offers a fresh perspective by separating ‘war’ as an institution from ‘use of force’ as a tool, arguing that war is becoming obsolete while force remains prevalent. It synthesizes empirical data and theoretical concepts to explain the apparent paradox of many conflicts but few interstate wars. The concept of ‘disinhibition’ is highlighted as a key trend.

Pour aller plus loin :

  • Uppsala Conflict Data Program — Provides detailed data on armed conflicts, essential for understanding conflict trends.
  • Charter of the United Nations — The legal basis for the prohibition of war and the framework for collective security.
  • Nuclear deterrence theory — Explores how nuclear weapons influence state behavior and reduce the likelihood of major wars.
  • Power politics — A theoretical perspective on international relations that emphasizes the role of power and state interests.
