Although Turkey and Israel did not establish full diplomatic relations until 1991, Turkey has cooperated with the State since its recognition of Israel in 1949. Turkey's ties to the other Muslim-majority nations in the region have at times resulted in pressure from Arab and Muslim states to temper its relationship with Israel. Relations between Turkey and Israel took a downturn after the 2008–09 Gaza War and Israel's raid of the Gaza flotilla. IHH, which organized the flotilla, is a Turkish charity that has been challenged on ties to Hamas and Al-Qaeda. Relations between Israel and Greece have improved since 1995 due to the decline of Israeli-Turkish relations. The two countries have a defense cooperation agreement and in 2010, the Israeli Air Force hosted Greece’s Hellenic Air Force in a joint exercise at the Uvda base. Israel is the second largest importer of Greek products in the Middle East. The joint Cyprus-Israel oil and gas explorations centered on the Leviathan gas field are an important factor for Greece, given its strong links with Cyprus. Cooperation in the world's longest sub-sea electric power cable, the EuroAsia Interconnector, has strengthened relations between Cyprus and Israel.
