I hadn't realised that Rumsfield was a master of the American language in the tradition of General Westmoreland and Dan Quale:
"I believe what I said yesterday; I don't know what I said, but I know what I think … and I assume that's what I said."
"I would not say that the future is less predictable than the past - I think the past was not predictable when it started."
"There will be some things that people will see. There will be some things people won't see. And life goes on."
"There are things that we know that we know. There are known unkowns … things that we now know that we don't know. But there are also unknown unknowns. There are things we don't know we don't know."
And here's a nice link for some Qualisms
