Winning friends in Afghanistan with Viagra:

...Such was the case with the 60-year-old chieftain who received the four pills from a U.S. operative. According to the retired operative who was there, the man was a clan leader in southern Afghanistan who had been wary of Americans -- neither supportive nor actively opposed. The man had extensive knowledge of the region and his village controlled key passages through the area. U.S. forces needed his cooperation and worked hard to win it, the retired operative said.

After a long conversation through an interpreter, the retired operator began to probe for ways to win the man's loyalty. A discussion of the man's family and many wives provided inspiration. Once it was established that the man was in good health, the pills were offered and accepted.

Four days later, when the Americans returned, the gift had worked its magic, the operative recalled.

"He came up to us beaming," the official said. "He said, 'You are a great man.' "

"And after that we could do whatever we wanted in his area."
