He learned from the best...Yassar Arafat, who at the time of his death, it is speculated that he had $6 billion. Where it all went is anybody's guess. His widow Suha, now 62 is still alive.
As Yassir died....the wife refused to cough up the body (PLO was on a schedule to bury him within 24 hours). Wife wanted passwords to all accounts...PLO started out refusing. In the end, rumors were that she got a signed document by PLO to give her around $100k a month.
