Question: When did relations take a downturn between Israel and the country north of Cyprus?

full_context: Document 1: Israel: 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.
Document 2: Syria: Syria (Arabic: سوريا ‎ Sūriyā), officially known as the Syrian Arab Republic (Arabic: الجمهورية العربية السورية ‎ al - Jumhūrīyah al - ʻArabīyah as - Sūrīyah) is a country in Western Asia, bordering Lebanon and the Mediterranean Sea to the west, Turkey to the north, Iraq to the east, Jordan to the south, and Israel to the southwest. Syria's capital and largest city is Damascus. A country of fertile plains, high mountains, and deserts, Syria is home to diverse ethnic and religious groups, including Syrian Arabs, Greeks, Armenians, Assyrians, Kurds, Circassians, Mandeans and Turks. Religious groups include Sunnis, Christians, Alawites, Druze, Isma'ilis, Mandeans, Shiites, Salafis, Yazidis, and Jews. Sunni make up the largest religious group in Syria.
Document 3: Greece: Meanwhile, Andreas Papandreou founded the Panhellenic Socialist Movement (PASOK) in response to Karamanlis's conservative New Democracy party, with the two political formations alternating in government ever since. Greece rejoined NATO in 1980. Greece became the tenth member of the European Communities (subsequently subsumed by the European Union) on 1 January 1981, ushering in a period of sustained growth. Widespread investments in industrial enterprises and heavy infrastructure, as well as funds from the European Union and growing revenues from tourism, shipping and a fast-growing service sector raised the country's standard of living to unprecedented levels. Traditionally strained relations with neighbouring Turkey improved when successive earthquakes hit both nations in 1999, leading to the lifting of the Greek veto against Turkey's bid for EU membership.
Document 4: Israel: Israeli foreign aid ranks very low among OECD nations, spending less than 0.1% of its GNI on foreign aid, as opposed to the recommended 0.7%. Individual international charitable donations are also very low, with only 0.1% of charitable donations being sent to foreign causes. However, Israel has a history of providing emergency aid and humanitarian response teams to disasters across the world. Israel's humanitarian efforts officially began in 1958, with the establishment of MASHAV, the Israeli Ministry of Foreign Affairs Agency for International Development Cooperation.
Document 5: Cyprus: According to the latest International Monetary Fund estimates, its per capita GDP (adjusted for purchasing power) at $30,769 is just above the average of the European Union.[citation needed] Cyprus has been sought as a base for several offshore businesses for its low tax rates. Tourism, financial services and shipping are significant parts of the economy. Economic policy of the Cyprus government has focused on meeting the criteria for admission to the European Union. The Cypriot government adopted the euro as the national currency on 1 January 2008.
Document 6: Israel: The United States and the Soviet Union were the first two countries to recognize the State of Israel, having declared recognition roughly simultaneously. The United States regards Israel as its "most reliable partner in the Middle East," based on "common democratic values, religious affinities, and security interests". Their bilateral relations are multidimensional and the United States is the principal proponent of the Arab-Israeli peace process. The United States and Israeli views differ on some issues, such as the Golan Heights, Jerusalem, and settlements. The United States has provided $68 billion in military assistance and $32 billion in grants to Israel since 1967, under the Foreign Assistance Act (period beginning 1962), more than any other country for that period until 2003.
Document 7: Cyprus: The majority of Cypriots receive their higher education at Greek, British, Turkish, other European and North American universities. It is noteworthy that Cyprus currently has the highest percentage of citizens of working age who have higher-level education in the EU at 30% which is ahead of Finland's 29.5%. In addition, 47% of its population aged 25–34 have tertiary education, which is the highest in the EU. The body of Cypriot students is highly mobile, with 78.7% studying in a university outside Cyprus.
Document 8: Cyprus: Cyprus (i/ˈsaɪprəs/; Greek: Κύπρος IPA: [ˈcipros]; Turkish: Kıbrıs IPA: [ˈkɯbɾɯs]), officially the Republic of Cyprus (Greek: Κυπριακή Δημοκρατία; Turkish: Kıbrıs Cumhuriyeti), is an island country in the Eastern Mediterranean Sea, off the coasts of Syria and Turkey.[e] Cyprus is the third largest and third most populous island in the Mediterranean, and a member state of the European Union. It is located south of Turkey, west of Syria and Lebanon, northwest of Israel and Palestine, north of Egypt and east of Greece.
Document 9: Armenia: Turkey also has a long history of poor relations with Armenia over its refusal to acknowledge the Armenian Genocide. Turkey was one of the first countries to recognize the Republic of Armenia (the 3rd republic) after its independence from the USSR in 1991. Despite this, for most of the 20th century and early 21st century, relations remain tense and there are no formal diplomatic relations between the two countries due to Turkey's refusal to establish them for numerous reasons. During the Nagorno-Karabakh War and citing it as the reason, Turkey illegally closed its land border with Armenia in 1993. It has not lifted its blockade despite pressure from the powerful Turkish business lobby interested in Armenian markets.
Document 10: Cyprus: International pressure led to a ceasefire, and by then 37% of the island had been taken over by the Turks and 180,000 Greek Cypriots had been evicted from their homes in the north. At the same time, around 50,000 Turkish Cypriots moved to the areas under the control of the Turkish Forces and settled in the properties of the displaced Greek Cypriots. Among a variety of sanctions against Turkey, in mid-1975 the US Congress imposed an arms embargo on Turkey for using American-supplied equipment during the Turkish invasion of Cyprus in 1974. There are 1,534 Greek Cypriots and 502 Turkish Cypriots missing as a result of the fighting.
Document 11: Cyprus: The majority of Greek Cypriots identify as Greek Orthodox, whereas most Turkish Cypriots are adherents of Sunni Islam. According to Eurobarometer 2005, Cyprus was the second most religious state in the European Union at that time, after Malta (although in 2005 Romania wasn't in the European Union, currently Romania is the most religious state in the European Union) (see Religion in the European Union). The first President of Cyprus, Makarios III, was an archbishop. The current leader of the Greek Orthodox Church of Cyprus is Archbishop Chrysostomos II.
Document 12: Turkey: Turkey (Turkish: Türkiye (ˈtyɾcije)), officially the Republic of Turkey (Turkish: Türkiye Cumhuriyeti (ˈtyɾcije d͡ʒumˈhuɾijeti) (listen)), is a transcontinental country in Eurasia, located mainly in Western Asia, with a smaller portion on the Balkan peninsula in Southeast Europe. Turkey is bordered by eight countries: Greece and Bulgaria to the northwest; Georgia to the northeast; Armenia, the Azerbaijani exclave of Nakhchivan and Iran to the east; and Iraq and Syria to the south. The country is encircled by seas on three sides, with the Aegean Sea to the west, the Black Sea to the north, and the Mediterranean Sea to the south. The Bosphorus, the Sea of Marmara, and the Dardanelles, which together form the Turkish Straits, divide Thrace and Anatolia and separate Europe from Asia. Ankara is the capital while Istanbul is the country's largest city and main cultural and commercial centre, classified as a leading global city.
Document 13: Israel: Germany's strong ties with Israel include cooperation on scientific and educational endeavors and the two states remain strong economic and military partners. Under the reparations agreement, by 2007[update] Germany had paid 25 billion euros in reparations to the Israeli state and individual Israeli Holocaust survivors. The UK has kept full diplomatic relations with Israel since its formation having had two visits from heads of state in 2007. The UK is seen as having a "natural" relationship with Israel on account of the British Mandate for Palestine. Relations between the two countries were also made stronger by former prime minister Tony Blair's efforts for a two state resolution. Israel is included in the European Union's European Neighbourhood Policy (ENP), which aims at bringing the EU and its neighbours closer.
Document 14: Cyprus: The Republic of Cyprus has de jure sovereignty over the island of Cyprus and its surrounding waters, according to international law, except for the British Overseas Territory of Akrotiri and Dhekelia, administered as Sovereign Base Areas. However, the Republic of Cyprus is de facto partitioned into two main parts; the area under the effective control of the Republic, comprising about 59% of the island's area, and the north, administered by the self-declared Turkish Republic of Northern Cyprus, which is recognised only by Turkey, covering about 36% of the island's area. The international community considers the northern part of the island as territory of the Republic of Cyprus occupied by Turkish forces. The occupation is viewed as illegal under international law, amounting to illegal occupation of EU territory since Cyprus became a member of the European Union.
Document 15: Israel: Israel is considered the most advanced country in Southwest Asia and the Middle East in economic and industrial development. Israel's quality university education and the establishment of a highly motivated and educated populace is largely responsible for spurring the country's high technology boom and rapid economic development. In 2010, it joined the OECD. The country is ranked 3rd in the region and 38th worldwide on the World Bank's Ease of Doing Business Index as well as in the World Economic Forum's Global Competitiveness Report. It has the second-largest number of startup companies in the world (after the United States) and the largest number of NASDAQ-listed companies outside North America.
