To underscore exactly how little difference there is between Hillary Clinton and Barack Obama's stated foreign policy positions, an Obama supporter e-mails this article where Hillary says:
"If we had actionable intelligence that Osama bin Laden or other high-value targets were in Pakistan I would ensure that they were targeted and killed or captured," she said.
That is, so far as I can tell, exactly Obama's position. The question isn't whether any of these candidates -- save maybe Kucinich -- would act on actionable intelligence in Waziristan. It's what they consider "actionable intelligence." The current argument is telling us exactly nothing, save that various candidates think they, and not the other candidates, should be president.
