The Kennedy administration tries to find a solution that will remove the missiles but avoid an act of war. They reject a blockade, as this is formally regarded as an act of war, and settle on what they publicly describe as a quarantine. They announce that the U.S. naval forces will stop all ships entering Cuban waters and inspect them to verify they are not carrying weapons destined for Cuba. The Soviet Union sends mixed messages in response. Off the shores of Cuba, the Soviet ships turn back from the quarantine lines. Secretary of State Dean Rusk (Henry Strozier) says, "We're eyeball to eyeball and I think the other fellow just blinked." The administration continues to order spy plane pictures, but one of Kennedy's top advisers, Kenny O'Donnell (Kevin Costner), calls the pilots to ensure the pilots do not report that they were shot at or fired upon, because if they were, the country would be forced to retaliate under the rules of engagement.
