Nicholas Burns questioned the wisdom of Romney’s tough talk about China and Russia, as the U.S. works to maintain their support for sanctions against Iran. “The complexity of that relationship [with China] does not lend itself to flip statements,” Burns said.

That leaves us with William Burns, a current deputy to Secretary of State Hillary Clinton; and Zoellick, the World Bank president who would not say last month whether he plans to advise Romney after leaving the World Bank on June 30.

One name that has not quite surfaced is John Bolton, America’s former ambassador to the U.N. under president George W. Bush. Bolton is not listed among Romney’s official coterie of advisers, but The New York Times’ David Sanger reported that he holds outsized sway over the candidate’s international views, to the chagrin of some moderates on Romney’s team.

If Romney’s thinking most closely mirrors that of the mustached American Enterprise Institute scholar and Fox News analyst, perhaps the idea isn’t so far fetched.
