According to this article, that may have something to do with why Arafat has not yet been declared officially dead.
The problem is that Arafat is still the only Palestinian official who can pay the bills. And it is unclear who, if anyone, has access to the estimated $2-3 billion in his personal Swiss bank accounts, according to a report in the current edition of Geostrategy-Direct.com. Even his wife is said to be unaware of how to access the funds.
Although this comes from the not-always-reliable World Tribune, there is obviously a great deal of truth to it. The interesting question is who allowed this almost entirely European aid money to end up in those Swiss accounts? Certainly no one who gave an RA about the Palestinian people.
