McCain's forensic questioning of Rumsfeld, who he later described as "one of the worst secretaries of defence in history", over Guantanamo Bay forced a change of administration policy.

In 2011, McCain was one of the strongest backers in Congress of US military intervention in Libya, calling on Washington to recognise Libyan rebels' transitional council as the true voice of the Libyan people and transfer frozen assets to them.
McCain was a supporter of George W Bush's decision to go to war with Iraq in 2003 and a later US troop surge.
