Ben Carson Is Struggling to Grasp Foreign Policy, Advisers Say

Ben Carson’s remarks on foreign policy have repeatedly raised questions about his grasp of the subject, but never more seriously than in the past week, when he wrongly asserted that China had intervened militarily in Syria and then failed, on national television, to name the countries he would call on to form a coalition to fight the Islamic State.

Faced with increasing scrutiny about whether Mr. Carson — who leads in some Republican presidential polls — was capable of leading American foreign policy, two of his top advisers said in interviews with The New York Times that he had struggled to master the intricacies of the Middle East and national security and that intense tutoring was having little effect.

“Nobody has been able to sit down with him and have him get one iota of intelligent information about the Middle East,” Duane R. Clarridge, a top adviser to Mr. Carson on terrorism and national security, said in an interview. He also said Mr. Carson needed weekly conference calls briefing him on foreign policy so “we can make him smart.”

As the deadly assaults in Paris claimed by the Islamic State reframe the presidential race, the candidates’ foreign policy credentials are suddenly under scrutiny. And Mr. Carson has attracted extra attention because his repeated dubious statements give rise to questions about where, as a retired neurosurgeon without government experience, he turns for information and counsel on complex global issues. What is unusual is the candor of those who are tutoring him about the physician’s struggle to master the subject.

In last week’s Republican debate, speaking of the turmoil in Syria, Mr. Carson said that “the Chinese are there.”

Both the White House and China denied that China had intervened militarily in Syria.

This week, Mr. Carson’s advisers said that his source for claiming Chinese involvement in Syria was a telephone conversation he had had with a freelance American intelligence operative in Iraq.

According to notes of the briefing kept by a Carson aide who was also on the line, the operative had said, “Multiple reports have surfaced that Chinese military advisers are on the ground in Syria, operating with Russian special operations personnel.”

Mr. Clarridge, a former C.I.A. agent who had connected Mr. Carson with the operative in Iraq, said on Monday that the information was wrong. The operative in Iraq had “overleaped” in suggesting Chinese troops are in Syria, Mr. Clarridge said, adding of the operative, “You know how it goes when people are desperate for some headline.”

Mr. Clarridge, described by Mr. Carson’s top adviser, Armstrong Williams, as “a mentor for Dr. Carson,” is a colorful, even legendary figure in intelligence circles, someone who could have stepped out of a Hollywood thriller. He was a longtime C.I.A. officer, serving undercover in India, Turkey, Italy and other countries. During the Reagan administration, he helped found the agency’s Counterterrorism Center and ran the C.I.A.’s Latin American division.
