Hi Moody. so we meet again. you may have some concerns, but in fact 1) this is not a biography of a living person 2) when in doubt, do not do massive deletions, but improve. You have completely removed the entire controversy section. In fact PNAC is a controversial organization. Whitewashing this fact does not make the controversy dissapear. I agree that comments should be sourced and well considered. 
PNAC is a historic and influential organization, as well as a controversial one. see http://www.pbs.org/wgbh/pages/frontline/shows/iraq/etc/cron.html for a sourced example of how they are considered to be influential.
