Washington, D.C. ? The Pentagon told Democratic presidential front-runner Hillary Rodham Clinton that her questions about how the U.S. plans to eventually withdraw from Iraq boost enemy propaganda.

In a stinging rebuke to a member of the Senate Armed Services Committee, Undersecretary of Defense Eric Edelman responded to questions Clinton raised in May in which she urged the Pentagon to start planning now for the withdrawal of American forces.

A copy of Edelman’s response, dated Monday, was obtained Thursday by The Associated Press.

“Premature and public discussion of the withdrawal of U.S. forces from Iraq reinforces enemy propaganda that the United States will abandon its allies in Iraq, much as we are perceived to have done in Vietnam, Lebanon and Somalia,” Edelman wrote.

He added that “such talk understandably unnerves the very same Iraqi allies we are asking to assume enormous personal risks.”

Clinton spokesman Philippe Reines called Edelman’s answer “at once outrageous and dangerous,” and said the senator would respond to Edelman’s boss, Defense Secretary Robert Gates.
