24 October. The day before JFK had made his quarantine order
enforceable as of 14:00.
He had chosen a "defensive quarantine",
an option softer than total blockade which was an act of war according
to the UN Charter. Quarantine, a concept listed in the OAS pact and less
drastic than blockade, did not mean total isolation of the enemy nation.
