The Iranian government has supported terrorist groups in many areas of the Middle East, but is now furious at Iraq and the United States for failure to deal with the Mojahedin Khaiq Organization (MKO) which is an Iranian group that seeks to overthrow the present government of Iran. The Iranian ambassador in Iraq has demanded these rebels be turned over to Iran for what most probably would be a death sentence. MKO members fought alongside Iraq troops during the war between the two nations in the 1980s. Iraq has told the MKO they will be expelled from their nation so it is best they move along.
The MKO could be a bargaining chip for Barack Obama in negotiations with the Iran government since America could ensure their supplies were cut off and they were dispersed to other parts of the world.
