Miller’s government, together with President Kwaśniewski, made a decision (March 2003) to join the international coalition and deploy Polish troops to Iraq, targeting at overthrowing Saddam Hussein’s government. Miller was also a co-signatory of "the letter of 8", signed by eight European prime ministers, supporting the US position on Iraq. Already in 2002, Miller gave permission to the U.S. government to run a secret CIA prison at Stare Kiejkuty military training center, three hours north of Warsaw. Years later he is facing accusations of acting anti-constitutionally by having tolerated the imprisonment and torture of prisoners.
