求拉姆斯费尔德的那段著名的饶口的话？

"As we know, There are known knowns. There are things we know we know. We also know There are known unknowns. That is to say We know there are some things We do not know. But there are also unknown unknowns, The ones we don't know We don't know."
- Donald H. Rumsfeld, February 12, 2002, Department of Defense news briefing

"我们知道,有些事情我们清楚我们知道.有些事情我们知道我们应该知道.我也清楚有些事我们不知道.这就是说我们知道有些东西我们不知道.但是也有些事情我们不知道我们不知道,那些我们不知道的事,我们就是不知道"
