He and Horseface say that money was payment on a nuclear arms deal that was signed right before the Shah of Iran was deposed. The total payment is $1.7 billion. All in foreign currency, because it is illegal to send over US dollars. Iran was suing for $10 billion. I think this whole deal stinks.
For the 4 hostages released to the US on Jan. 17th, they gave the Iranians 7 citizens back, and dropped extradition requests for 14 others. Captain muslim and Horseface sure have strange bargaining skills.
