 Kennedy addressed the sense of urgency about the growing hostile situation by standing firm and tightening the naval blockade as well as conveying to Khrushchev the continued threat of a possible invasion of Cuba.As a result of Kennedy's successful use of coercive diplomacy added to negotiated concessions, Khrushchev agreed to remove missiles in place and to discontinue the deployment of new missiles into Cuba while the U.S. agreed to remove its Jupiter missiles stationed in Turkey and to call off any invasion of Cuba.During the 1990–91 Gulf War, coercive diplomacy failed to persuade Saddam Hussein to exit Kuwait and move his military forces back to Iraq; though the use of deterrence effectively convinced the Iraqi president that he could not invade further south into Saudi Arabia, it did little to expel him from Kuwait.
