paragraph_text: Arab–Israeli conflict
  
  During the 1950s, Israel was frequently attacked by Palestinian fedayeen, nearly always against civilians, mainly from the Egyptian-occupied Gaza Strip, leading to several Israeli reprisal operations. In 1956, the UK and France aimed at regaining control of the Suez Canal, which Egypt had nationalised. The continued blockade of the Suez Canal and Straits of Tiran to Israeli shipping, together with increasing fedayeen attacks against Israel's southern population and recent Arab threatening statements, prompted Israel to attack Egypt. Israel joined a secret alliance with the UK and France and overran the Sinai Peninsula in the Suez Crisis but was pressured to withdraw by the UN in return for guarantees of Israeli shipping rights. The war resulted in significant reduction of Israeli border infiltration.
  
  In the early 1960s, Israel captured Nazi war criminal Adolf Eichmann in Argentina and brought him to Israel for trial. Eichmann remains the only person executed in Israel by conviction in an Israeli civilian court. In 1963, Israel was engaged in a diplomatic standoff with the United States in relation to the Israeli nuclear programme.
  
  Since 1964 Arab countries, concerned over Israeli plans to divert waters of the Jordan River into the coastal plain, had been trying to divert the headwaters to deprive Israel of water resources, provoking tensions between Israel on the one hand, and Syria and Lebanon on the other. Arab nationalists led by Egyptian President Gamal Abdel Nasser refused to recognise Israel and called for its destruction. By 1966 Israeli-Arab relations had deteriorated to the point of battles taking place between Israeli and Arab forces.
  
  In May 1967, Egypt massed its army near the border with Israel, expelled UN peacekeepers stationed in the Sinai Peninsula since 1957, and blocked Israel's access to the Red Sea. Other Arab states mobilised their forces. Israel reiterated that these actions were a casus belli and launched a pre-emptive strike (Operation Focus) against Egypt in June. Jordan, Syria and Iraq attacked Israel. In the Six-Day War, Israel captured and occupied the West Bank from Jordan, the Gaza Strip and Sinai Peninsula from Egypt, and the Golan Heights from Syria. Jerusalem's boundaries were enlarged, incorporating East Jerusalem. The 1949 Green Line became the administrative boundary between Israel and the occupied territories.
  
  Following the 1967 war and the " Three Nos " resolution of the Arab League, Israel faced attacks from the Egyptians in the Sinai Peninsula during the 1967–1970 War of Attrition, and from Palestinian groups targeting Israelis in the occupied territories, globally, and in Israel. Most important among the Palestinian and Arab groups was the Palestine Liberation Organisation (PLO), established in 1964, which initially committed itself to "armed struggle as the only way to liberate the homeland". In the late 1960s and early 1970s, Palestinian groups launched attacks against Israeli and Jewish targets around the world, including a massacre of Israeli athletes at the 1972 Summer Olympics in Munich. The Israeli government responded with an assassination campaign against the organisers of the massacre, a bombing and a raid on the PLO headquarters in Lebanon.
  
  On 6 October 1973, the Egyptian and Syrian armies launched a surprise attack against Israeli forces in the Sinai Peninsula and Golan Heights, opening the Yom Kippur War. The war ended on 25 October with Israel repelling Egyptian and Syrian forces but suffering great losses. An internal inquiry exonerated the government of responsibility for failures before and during the war, but public anger forced Prime Minister Golda Meir to resign. In July 1976, an airliner was hijacked in flight from Israel to France by Palestinian guerrillas; Israeli commandos rescued 102 of 106 Israeli hostages.
