We can always cross out our answers. I didn't see anything stopping us from doing that.
We have to be careful about what age we are in. If we are good American living in a modern age, JFK wouldn't be too bad as a choice.
As for the five man in the bunker question, I would've choose Priest instead of Marines in Beskars list. After few years living in the bunker, there could be heaps of trouble. Priest looks like the one who can resolve the problem. Marine who was dishonorably discharge could know couple of handy skills, but I don't think its worth it to keep him, considering the risk of him getting abusive and all in the future. But denying him, may cause him shooting us off.
