Episode notes
Legal Blockade Is A Narrow Defined Tool
- A legal blockade is distinct from colloquial uses and requires strict criteria under naval law.
- Ian Ralby lists declaration, geographic/time bounds, humanitarian allowances, impartiality, proportionality, and effectiveness as required elements.
Two Layers Created Near Closure Of Hormuz
- Two overlapping impediments now restrict transit through the Strait of Hormuz: Iranian attacks/closures and a U.S. blockade focused on Iranian ports.
- The combined effect has produced a near complete practical closure despite different legal claims.
Mines Make Clearing Risky And Fragile
- Allegations of mines require countermining before commercial transit, which is dangerous and time-consuming.
- Ralby warns countermining vessels are exposed and any mishap could destabilize an already fragile ceasefire.
