THE thing the hawks or neo-cons DON'T want is someone like Obama as president.  He certainly doesn't share THEIR values.  They respond on a visceral level to perceived threats.  He is analytical.  They see him as a threat to the very continued existence of the USA, that continued existence being guaranteed only by having ever vigilant hawks in control of the armed forces.  

On a visceral level, they fear and loathe Obama and the possibility that he might get elected.  If Georgian president Saakashvili and/or his newly US trained army, along with an untold number of Georgans, including Osetians and Abkhazians have to be heroically sacrificed to feckless Georgian agression and to the Russian Bear as pawns in the game, that is regretful.  They will remember their sacrifice.  

As the Dutch said while fighting the Spanish: "It is not necessary to have hope in order to persevere."
