of Israel's impending total defeat, but "Temple" was also the code word for Israel's nuclear weapons. Dayan raised the nuclear topic in a cabinet meeting, warning that the country was approaching a point of "last resort". That night, Meir authorized the assembly of thirteen tactical nuclear weapons for Jericho missiles at Sdot Micha Airbase and F-4 Phantom II aircraft at Tel Nof Airbase. They would be used if absolutely necessary to prevent total defeat, but the preparation was done in an easily detectable way, likely as a signal to the United States. Kissinger learned of the nuclear alert on the morning of October 9. That day, President Nixon ordered the commencement of Operation Nickel Grass, an American airlift to replace all of Israel's material losses. Anecdotal evidence suggests that Kissinger told Sadat that the reason for the U.S. airlift was that the Israelis were close to "going nuclear". However, subsequent interviews with Kissinger, Schlesinger, and William Quandt suggested that the nuclear aspect was not a major factor in the decision to re-supply. These officials cited the ongoing Soviet re-supply effort and Sadat's early rejection of a ceasefire as the primary motivators. European countries refused to allow U.S. airplanes carrying supplies for Israel to refuel at their bases, fearing an Arab oil embargo, with the exception of Portugal and the Netherlands. Portugal permitted the United States to use the leased base of Lajes Field in the Azores, and the defence minister of the Netherlands, apparently acting without consulting his cabinet colleagues, secretly authorised the use of Dutch airfields. Greece, then under the dictatorial rule of the Regime of the Colonels, declared itself neutral in the conflict. However, the Greek junta permitted the United States to use communications facilities within Greece and the airports at Athens and at Souda Naval Base to facilitate its assistance to Israel, though it refused to allow the Americans to use its strategically important bases in Cyprus. Israel began receiving supplies via U.S. Air Force cargo airplanes on October 14, although some equipment had arrived on planes from Israel's national airline El Al before this date. By that time, the IDF had advanced deep into Syria and was mounting a largely successful invasion of the Egyptian mainland from the Sinai, but had taken severe material losses. According to Abraham Rabinovich, "while the American airlift of supplies did not immediately replace Israel's losses in equipment, it did allow
