Not at all alarming. All the viable candidates are vetted by the foreign policy elite. It would be surprising if any of them didn't have imperialist advisers. As far as I can tell, if Wall Street doesn't like you and if you don't accept the Post-WWII foreign policy strategy, then you don't get to first base. John Edwards failed the Wall Street smell test. I'm not sure about his foreign policy credentials, as he had much less to say about that than he did about domestic issues of interest to working people.
