For over six months BBC Radio has been running a section called "The Donald Rumsfeld sound-bite of the week", the most telling of which is:
'I believe what I said yesterday, I don't know what I said, but I know what I think and, I assume it's what I said.' [Listen RealAudio]
and another one:
Q: Where is Bin Laden?
Rumsfeld: We do know of certain knowledge that he is either in Afganistan, or some other country, or dead. [Listen RealAudio]
