billion, with investments in companies like a Coca-Cola bottling plant in Ramallah, a Tunisian cell phone company and venture capital funds in the U.S. and the Cayman Islands. The head of the investigation stated that "although the money for the portfolio came from public funds like Palestinian taxes, virtually none of it was used for the Palestinian people; it was all controlled by Arafat. And none of these dealings were made public." An investigation conducted by the General Accounting Office reported that Arafat and the PLO held over $10 billion in assets even at the time when he was publicly claiming bankruptcy. Although Arafat lived a modest lifestyle, Dennis Ross, former Middle East negotiator for Presidents George H.W. Bush and Bill Clinton, stated that Arafat's "walking-around money" financed a vast patronage system known as neopatrimonialism. According to Salam Fayyad—a former World Bank official whom Arafat appointed Finance Minister of the PNA in 2002—Arafat's commodity monopolies could accurately be seen as gouging his own people, "especially in Gaza which is poorer, which is something that is totally unacceptable and immoral." Fayyad claims that Arafat used $20 million from public funds to pay the leadership of the PNA security forces (the Preventive Security Service) alone. Fuad Shubaki, former financial aide to Arafat, told the Israeli security service Shin Bet that Arafat used several million dollars of aid money to buy weapons and support militant groups. During Israel's Operation Defensive Shield, the Israel army recovered counterfeit money and documents from Arafat's Ramallah headquarters. The documents showed that, in 2001, Arafat personally approved payments to Tanzim militants. The Palestinians claimed that the counterfeit money was confiscated from criminal elements. Illness and death Unsuccessful Israeli assassination attempts The Israeli government tried for decades to assassinate Arafat, including attempting to intercept and shoot down private aircraft and commercial airliners on which he was believed to be traveling. The assassination was initially assigned to Caesarea, the Mossad unit in charge of Israel's numerous targeted killings. Shooting down a commercial airliner in international airspace over very deep water was thought to be preferable to make recovery of the wreckage, and hence investigation, more difficult. Following Israel's 1982 invasion of Lebanon, Israeli Minister of Defense Ariel Sharon created a special task force code named "Salt Fish" headed by special ops experts Meir Dagan and Rafi Eitan to track Arafat's movements in Lebanon to kill him because Sharon saw Arafat
