From the debate transcript:

TRUMP: Well, all of these bad leaders from ISIS are leaving Mosul. Why can't they do it quietly? Why can't they do the attack, make it a sneak attack, and after the attack is made, inform the American public that we've knocked out the leaders, we've had a tremendous success?

People leave. Why do they have to say we'e going to be attacking Mosul within the next four to six weeks, which is what they're saying? How stupid is our country?

RADDATZ: There are sometimes reasons the military does that. Psychological warfare.
