Shalom Chaim,
I read a couple of weeks ago that Jimmy Carter's friend, national security adviser and influential Democrat, Zbignewi Brzezinski, is supporting Barack Obama for president. In his attempts to bring down Hillary, he's actually stated that being a "First Lady" does not prepare someone to be president nor does it give someone good experience.
I found an article from the USA Today that contains the names of "foreign-policy" advisers.
Brzezinski is an "informal" adviser to Barack. He also has Anthony Lake (former national security adviser to Bill Clinton), Ivo Daadler (Clinton adviser on Europe), Greg Craig (Albright adviser and Clinton White House counsel) and Susan Rice (Clinton adviser and former assistant secretary of state), all former advisers to Bill Clinton.
Hillary's team includes her husband, Richard Holbrooke, Madeleine Albright, Sandy Berger and Strobe Talbott, who is a former deputy secretary of state.
McCain has Kissinger, George Schultz and Lawrence Eagleburger
Giuliani is being counseled by a former State Department foreign policy adviser named Christopher Hill. Giuliani also has Norman Podhoretz who seems to recognize the threat of Iran and Giuliani also has Martin Kramer, who has been very critical of Islam. Kramer is also against the idea of trying to democratize the "Middle East." So Giuliani seems to have a variety of viewpoints.
Steven Schrage, a former State Department international law specialist, is advising Republican Mitt Romney. I'm not sure yet who else Romney has.
Derek Chollet, who was John Edwards' foreign policy adviser when the Democrat served in the Senate, is now a key adviser in Edwards' campaign.
I haven't found information about Fred Thompson yet.
I'm still hoping Duncan Hunter could become competitive enough for a serious challenge for the GOP nomination but especially with so many primaries having been moved up, it will be a long-shot.
