An article recently posted on Infognomon (which can be accessed here) written by M.Michail provides some information on the role of Israel around the days immediately preceding and following the invasion of Cyprus.
The German magazine, Der Spiegel in 19 August 1974, revealed that “... hiding behind this issue (i.e. the Turkish invasion of Cyprus) was Israel” and that “... the telephone line between Nicosia - Tel Aviv had been connected two days before the coup and only the embassy of Israel or Israeli journalists could use it” (from the Greek newspaper Kathimerini, 20/4/1975). This probably means that Israel and its embassy in Nicosia were aware of the coup to oust Makarios [this is interesting but probably many secret services knew about the invasion of Cyprus]
The Jews were, with a series of “errors” and “coincidences” during the Turkish invasion, continuously on the side of ATTILA [the code name used for the Turkish military operation]. The Athenian newspaper Ta Nea (27/2/1975) published that Israeli planes, at the beginning of July 1975, “accidentally” violated the Greek airspace of Cyprus and twice during the Turkish invasion of July 1974. However, amazingly the following event was also made to appear as “coincidental”: an Israeli navy boat coincided (!) to be within the Turkish invasion armada. And, indeed, collected the castaways of the Turkish destroyer, which was accidentally bombed by Turkish airplanes (from the newspaper Greek Tharros, 15/12/1979). The 42 survivors of the sinking of the Turkish destroyer "Kotzatepe",which previously belonged to the U.S. Navy, was transferred to the Israeli vessel in Haifa! [this is particularly strange as one would expect that Turkish ports would have been closer and more convenient]
At the end of 1972, the secret services of Israel sold to EOKA B "Kalasnikovs" "under the direction of the CIA". The Cypriot journalist Spyros Papageorgiou wrote in his book “The Attila impacts Cyprus”, p. 27: “In connection with the acquisition of Kalashnikovs, despite being sold by the Israeli secret service, they were acting under the direction of the CIA. However, it can be said with certainty, regarding the negotiated purchase of weapons in Beirut, the leader of the operation of EOKA B, Kikis Constantinou was under the impression that he was dealing with illegal arms traffickers". Of course, the readers can draw their own conclusions. The attitude of Israel during the Turkish invasion of 1974 cannot be described as positive. The same “coincidental” attitude was there during in the invasion of Turkey in 1963-64. [unfortunately the article does not provide details of this assertion]
Without further evidence some of the inferences made above appear tenuous. However, we can state with reasonable certainty that Israel's role during the invasion of Cyprus was not constructive.
Israel's enmity towards Greece and the Cypriots throughout the 1950’s to the 1980’s, should not preclude Greece and Israel forging closer diplomatic and even military ties going forward - international relations should be based on interests rather than historical grudges, loyalty or sentiment. However, history should not be forgotten and Greece must choose its "friends" wisely.
