He expressed his disappointment over the loss of life but not on the strong commitment he gave to disarming Saddam Hussein. Blair said he assured support to the former US President George Bush in the Iraq. Tony Blair who left office in 2007 and is now a West Asia peace envoy, also issued a warning about the growing threat posed by Iran. He suggested force may be necessary to confront Iran's nuclear program.
