From Haaretz's english online edition:
In spite of the belligerent declarations of Iran's leaders - President Mahmoud Ahmadinejad repeated his mantra this week that he expects the Zionist entity to collapse in the near future - Iranian representatives are holding negotiations with Israeli representatives. These are not only indirect negotiations, but real meetings. These meetings have been going on for about two decades, and concern laborious international arbitration regarding the debts between the two nations.
There are three separate litigations, which are taking place simultaneously in several European countries, all of them pertaining to a complex legal and business entity called Trans-Asiatic Oil Limited, and relating to one of the biggest secrets between Israel and Iran: the past oil connections between the two countries. Three years ago one of the arbitrations ruled that Israeli fuel companies have to pay the Iranian National Oil Company tens of millions of dollars. All the parties made efforts to maintain the secrecy of the decision and every other detail connected to the subject.
