decline in military combat

Steven Pinker

• Core Argument: Humanity is living in the "Long Peace," a historical era where war and violence have declined dramatically.

• Mechanism: Cultural and Moral Evolution. The decline of war is driven by the "better angels of our nature"—the rise of literacy, global trade, human rights, and a civilizing process that makes violence socially unacceptable.

• View on Medicine: Treats low battle-death data as literal proof of a more peaceful world; views medicine as a secondary factor rather than the cause of the decline.

Joshua Goldstein

• Core Argument: War is actively declining because the international community has built a highly effective apparatus to prevent and stop it.

• Mechanism: Institutional Peacekeeping. The drop in battle deaths is a direct result of global cooperation, international institutions (like the UN), international law, and active peacekeeping operations.

• View on Medicine: Accepts raw battle-death metrics as objective evidence that the world has become less violent and that fewer conflicts are occurring.

Tanisha Fazal

• Core Argument: War is not declining in frequency; it has simply become fundamentally more survivable.

• Mechanism: Military Medicine and Technology. Leaps in battlefield care (the "Four Pillars": preventive medicine, armor/tourniquets, rapid medevac, and trauma surgery) have fundamentally altered data by shifting thousands of soldiers from the "killed" column to the "wounded" column.

• Key Metric: Wounded-to-Killed Ratio. Proves that while the historic ratio was 3:1, modern conflicts see ratios of 10:1 to 17:1, meaning the political act of war remains constant but medicine masks its lethality.

Stephen Biddle

• Core Argument: Warfare is an enduring feature of international politics, and its apparent drop in lethality is due to how armies fight, not a lack of conflict.

• Mechanism: The "Modern System" of Force Employment. To survive a hyper-lethal battlefield ("storm of steel"), armies have adapted since 1900 through extreme dispersion, tactical concealment, cover, and small-unit suppression.

• View on Technology: Weapon technology is deadlier than ever; it is human tactical adaptation—not a shift in global morality—that keeps soldiers alive under heavy fire.
