Ex-British PM Tony Blair, however, denied accusations that he was a 'poodle' of Washington whose subservience caused him to lead Britain into a disastrous conflict.
Blair said on Wednesday he believed that it was important for the United States to have allies in the fight against international terrorism after the September 11, 2001 attacks in New York.
"I believed that Britain, as America's strongest ally, should be with it in tackling this new and unprecedented security challenge [terrorism]. I believed it important that America was not alone, but part of a wider coalition. In the end, even the majority of European Union nations supported action in Iraq," Blair said.
