In a 2004 Salon magazine article, How Ahmed Chalabi Conned the Neocons, journalist John Dizard reported on the connection between Chalabi and Douglas Feith and Feith's Jerusalem-based law partner, Marc Zell. Dizard explains the centerpiece of the collaboration, in the words of the now-embittered Zell:
Zell outlines what Chalabi was promising the neocons before the Iraq war: "He said he would end Iraq's boycott of trade with Israel, and would allow Israeli companies to do business there. He said the new Iraqi government would agree to rebuild the pipeline from Mosul in the northern Iraqi oil fields to Haifa the Israeli port, and the location of a major refinery." But Chalabi, Zell says, has delivered on none of them.
In the early days of its statehood, Israel and Iran were business partners in a highly lucrative oil transport and supply operation that fell apart in 1979.
Here's how that Iran-Israel oil supply arrangement came about, fell apart, and became the subject of lawsuits which were decided in Iran's favor, but which Israel has not yet paid.
