I wonder if Norman heard the whole exchange or just the cut down "army you have" part. Because, frankly, I can't for the life of me see what's wrong with what Rumsfeld said, which was more or less, "sometimes you won't know what you need until you need it."
Rumsfeld essentially said that (a) yes, we need more armored hmmwvs, and (b) we are producing them as rapidly as possible. What is wrong with that? The second part: that we are producing them as rapidly as possible. As has been demonstrated in numerous articles over the past several days, this is simply not true.
When a war starts...it starts. You can't put it on pause and fix what needs to be fixed. You go with what you have and work on improving it as you go along.
So, what you're saying is that nobody could have realized in advance that armored vehicles would be needed to secure Iraq?
