well If I compare Clinton lying about having sex with Monica,
and Bush lying about WMDs in Iraq (of course the US knew he had them, theyve got the REceipts!) Id say the one big difference is the lives of 600+ American kids and possibly 10,000 Iraqis. (not to mention alienating most of Europe and the rest of the world )

and to put it in further perspective - Bush fought the 911 commission right from its creation and funding (Kenneth Starr commission on Clinton spent $55million more than the 911 commission)

and the idea the Condi Rice testifying might set a bad precedent?
actually the national security advisor under Roosevelt had no problem testifying to a post war investigation of the Pearl Harbour attack.
