This chapter discusses Greece’s efforts to redefine its relationship with Washington according to Greek security needs. The Karamanlis government made it clear to the Americans that Greece’s contribution to Western defence would be analogous to the support that it would receive from Washington in its confrontation with Turkey. The establishment of the 7 to 10 ratio for US military aid to Greece and Turkey respectively and the 1976 US-Greek agreement emphasized Washington’s willingness to satisfy Greek demands and adopt a balanced approach to the Greek-Turkish dispute. This chapter also examines in detail the Greek-Turkish war crisis of August 1976 as a case study of the Europeanization of Greek foreign policy and the triangular relationship that developed between Greece and Turkey on the one hand and Western governments on the other. The Sismik crisis showed that the Greek strategy of political containment of Turkey was partially successful. The arrangements agreed in 1976 between Greece on the one hand, and Turkey and the Western governments on the other, proved longstanding and created a political framework that allowed Athens to buy time until it had completed its integration into the West.
