Tariq Ramadan is a Swiss philosophy professor who has visited America 20 times, briefed the CIA, and lectured at major American universities. He was nine days away from assuming his new post at Notre Dame University in Indiana when the U.S. government pulled his visa. Since then, he has heard nothing about his appeal. Ramadan is worried about America's descent into unilateralism. We all should be. (LA Times , free reg. req'd)
