Here was the question and the answer. Everything else was just elaboration.
RUSSERT: The point being, in November, Pakistan was able to airlift people out of Afghanistan. Did that happen?
SECY RUMSFELD: I do not believe it happened.
Apparently, the mistake Rumsfeld made is that he started providing reasons why he doesn't believe it happened. That is being parsed so that we can believe that he's really lying, and that evil b*ast*rd President Musharraf, is someone who deserves to be nuked.
But Rumsfeld's answer was not ambiguous. Those who are trying to make it so, are doing so for their own reasons.
