U.S. National Security Adviser, Stephen Hadley said that there are many things that the United States can do to root out Iran from Iraq. In an Interview on April 13, with the Fox News T.V. he added that the US troops are after eviction of Iranian backed special groups who are fighting in Iraq as Iranian regime’s proxies.

Asked what the President meant when he said the US is going to defend its interests in Iraq and what reaction he is ready to do, he answered that as the President said Iranian regime has one choice ahead. The US troops are pursuing Iranian backed special groups, their networks and operations which are killing US and Iraqi troops in Iraq. The US troops are going to destroy their network and stop transfer of arms and fund into Iraq.
Iranian regime active presence in southern Iraq through its proxy armed militias, who were trained in Iran, is the main cause of murders of Iraqi forces and civilians.
