Hare was United States Ambassador to North Yemen in 1959, and then returned to the State Department in Washington in 1960.[1] Later in 1960, Turkey threatened to invade Cyprus, and in the midst of the crisis, Hare was named United States Ambassador to Turkey.[6] He played a critical role in convincing the Turkish government not to invade Cyprus, though his efforts were later nearly undone by a strongly worded letter from President Lyndon B. Johnson.[6] Hare was Ambassador to Turkey until 1965.[6]
