To the officials, I realize the problems you're having here. You're being asked really to decide upon the legitimacy or lack of legitimacy of the war when of course these things haven't been decided in the public domain. Everyone has their political opinions on whether the Iraq War is legal and whether the Vietnam War was legal or legitimate.
So I realize the problem the officials would have, and they seem to be demonstrating that they have some problems answering these questions.
I'm not going to direct you, and I shouldn't direct you, on how to answer the questions, but you're free to answer the questions in whatever way you feel is appropriate.
