Chokepoint control doctrine shifting from physical blockade to managed uncertainty as a coercive instrument

Analysis

The article documents a structural evolution in how states weaponize maritime chokepoints: rather than attempting full closure (which invites conventional military response), actors can achieve equivalent economic coercion by selectively degrading navigational confidence through mines, electronic warfare, and administrative toll systems. This lowers the threshold for chokepoint coercion while raising the cost of counter-response.

"maritime traffic collapsed by almost 95 percent – not because of sustained naval confrontation in the strait, but because shipowners, insurers, and seafarers" [95 percent]
Reasoning from this article

The article generalizes this beyond Iran: any state controlling a chokepoint with asymmetric tools (mines, GNSS spoofing, AIS suppression, selective tolls) can now impose near-blockade effects without triggering the conventional military response that a formal closure would invite. This redefines deterrence calculus at all major maritime chokepoints globally — Malacca, Bab-el-Mandeb, Taiwan Strait — where similar hybrid toolkits exist or could be assembled.
