Someone was asked something along these lines by a member of some legislative body:
How will your research help protect this country?
That someone replied with something like this:
It won’t, but it will keep this country worth protecting.
The exact wording in those quotes probably differ from what was actually said.
This isn’t a rhetorical question, nor is it an exercise in trivia. I don’t know who said it, what the exact context of the quote was, or whether this was actually said by anyone, anytime, anywhere. So, if you know of the exact quote, who said it, and where it was said, please leave a note in the comments. Thanks!
