Yes it does. And actually he was of "Pennsylvania dutch" ancestry, whatever that means. Perhaps you would know more about that then I.
I would offer that if these aliens could pluck whomever/whenever, why would they need permission?
Consider that if abducting was necessary to these "aliens", and being polite about it was a priority then there must have been some type of reconciliation.
Why would Eisenhower give them permission, what could he have possibly gotten in return for his countrymen, and why would they trade in the first place. Why not just take what you want.
It doesn't add up to me.
That ain't dutch anchestry but German/Swish,the dutch is probably misnamed and should be spelled Duits or Deutz.
From what i understand these aliens were/are aparently not infallible ie

not bullet proof) and just sought shelter from whatever calamity.But they had a wealth of technology alien to earth,so a "beneficial" trade was seemed the thing to do...what is a handfull of people worth versus this new techology eh
Military might is what everbody is after,the aliens could provide the means in the form of new metals and maybe computer technology and propulsion technics,who knows,..gov-ment ain't spilling the beans.
People is just a renewable resource
