Osama Bin Laden
Rumsfeld, who arrived Wednesday morning local time for an unannounced visit to Pakistan, said he found it interesting that bin Laden has not been heard from publicly in nearly a year.
"I don't know what it means," Rumsfeld told a group of reporters traveling with him. "I suspect that in any event, if he's alive and functioning that he's probably spending a major fraction of his time trying to avoid getting caught. I have trouble believing that he's able to operate sufficiently to be in a position of major command over a worldwide al-Qaida operation, but I could be wrong. We just don't know."
