A Greek–Israeli cooperation agreement on military affairs was concluded as early as December 1994 (predating the Turkish–Israeli agreement of February 1996); however, both sides refrained from activating the agreement. Greece was apparently concerned about alienating the Arab world while Israel did not wish to upset the Turks. Greece and Israel agreed to hold joint naval maneuvers at the end of the summer 1997, but they were indefinitely postponed by the Greeks. The reason given for the postponement was that the Greek navy was busy preventing infiltrations from Albania, and it could not spare a frigate for the exercises.
