Definition
International Humanitarian Law (IHL) is the body of treaty and customary law — centered on the Geneva Conventions and their Additional Protocols — that regulates the conduct of armed conflict. Its core principles include distinction (between combatants and civilians), proportionality (military advantage vs. civilian harm), and protection of objects indispensable to civilian survival (water, food, medical facilities).
Why It Matters for the Newsletter
Power / Geopolitics: IHL is the legal framework against which infrastructure-targeting decisions in the 2026 Iran war are being evaluated. Trump’s threats against desalination plants, power plants, and bridges have been flagged by international law experts as potential war crimes violations because they target objects civilians depend on for survival.
Infrastructure: IHL is the place where the Infrastructure Warfare thesis meets a binding legal constraint — at least nominally. The gap between IHL on paper and what state actors actually do is one of the recurring tensions the wiki tracks.
Evidence & Examples
- Trump’s threats against Iranian desalination plants flagged by international law experts as potential IHL violations Trump threatens hell on Iran infrastructure if Strait remains blocked
- IHL principles cited in coverage of US-Israeli targeting decisions throughout the Iran war
- Russia-Ukraine war as the major recent test case for IHL enforcement (Nord Stream, power grid strikes, Kakhovka dam)
Tensions & Counterarguments
- Enforcement is structurally weak: the ICC and UN mechanisms have limited reach against major-power belligerents
- Dual-use infrastructure (power plants serving both military and civilian functions) creates large interpretive gaps
- The proportionality test is famously elastic; near any military objective can be justified as proportionate
Related Concepts
- Infrastructure Warfare — the conduct IHL is meant to constrain
- Coercive Diplomacy — IHL violation threats deployed as bargaining leverage
- Chokepoint Control — chokepoint targeting often raises the dual-use question
