Cliff Kupchan, vice president of the Nixon Center and Clinton's former expert on Tehran, said that "if diplomacy fails, there might be no choice but for the United States to lead a concerted military campaign against Iran," the Associated Press reported.

Kupchan said, "If the U.S. moves aggressively, it won't be sanctions; it will be a coalition of the willing."

Where have we heard that phrase before?
