"At one time, the Americans declassified documents about their contacts with Saddam Hussein's regime, including through military channels. And then, when the need arose to enter Iraq, they classified them again," Artizov said.
He added that "no one stands on ceremony" when it comes to defending national interests.
In March 2003, the US and its allies invaded Iraq, claiming that it possessed weapons of mass destruction (WMDs).
They captured Baghdad and overthrew Saddam Hussein, who was executed in 2006 on accusations of having committed numerous crimes based on political, ethnic, and religious grounds. International inspectors never found any evidence of WMDs.
