To be sure, Rice is not her own person. She is doing at the UN exactly what President Obama wants done — as are Eric Holder at the Justice Department, Hillary Clinton at State, Janet Napolitano at Homeland Security, and so on.
That, though, is not an excuse to confirm her if she is nominated. It is an additional powerful reason to oppose her. She deserves to be defeated on her own demerits, but more significantly she deserves to be defeated as an admonition that the world should not confuse Barack Obama’s reelection with popular support for Barack Obama’s foreign policy.
