How much damage could a British blockade of Argentina do, and how would it be enforced?
Short answerA submarine inner ring and surface outer ring could do major economic damage, but regional trade disruption made the plan politically untenable.
NotesSubmarines would form an inner barrier close to Argentina. Surface forces would control a more distant outer ring and police traffic beyond the submarine patrol area. Such a blockade could inflict serious economic damage. It would also interfere with wider South American trade and draw neutral states into the consequences. The concept is militarily feasible but politically prohibitive.
