The special relationship with America is a goody. Current activity in Iraq etc. Just to show you understand the job you may be called upon to do and why. They may ask your personal opinion. Be honest.
Got to sign off now. Good luck and let us know how you get on.
One other point if I may. After what you ahve been through, you are entitled to a sympathy vote. It is, however, a very personal matter so do not feel you have to talk about it at the interview if it makes you upset or uncomfortable. They will understand.
