Who is the cause of the disaster in oil sales? Ahsan Salehi, Secretary of the Information Council of the 13th Government wrote: Gurbanzadeh's (member of the Persian Gulf Holdings Board) statistics on oil sales are shocking: from 1997 to 2003, sales were $220 billion, and $480 million were not returned. But in 2004 sales were $31 billion, and $4.7 billion never came back. Who is the cause of this disaster that caused the coup and the war on February 28? Where were and were the regulatory institutions?
