"We're developing a national missile defense system. Do you think that the system needs to be operationally effective, suitable, survival, and cost-effective?"

"I want to compliment General Ward and Admiral Stavridis as you are adapting to this new policy where you're not only a warrior, you're also a diplomat."

"Do you think that we need to take the steps needed to make sure that the system is all of those things?"

"The bottom line question is: Is it operationally effective so that in fact if we had the threat it could do the job?"
