Because Obama campaigned on a Realist foreign policy and McCain campaigned on a NeoCon foreign policy.
You mean the White House’s Weapons-of-Mass-Destruction PR man suddenly isn’t a “neo-con,” but rather has adopted “realism”.
What’s the difference between the two again? Oh yeah, realists infiltrate everywhere around the globe for mankind and international order, whereas neo-cons infiltrate everywhere around the globe for national security and freedom (or whatever).
