The INA of 1952 describes who is a citizen if born abroad (it has been
amended since its original enactment.) The law in effect in 1961 is
clear: a child born abroad to parents of whom only one was a US citizen
would not be a citizen at birth unless the citizen-parent had lived five
years in the USA after the age of 14, *regardless* of the
citizen-parent's marital status. As the Maoist Stanley Ann Dunham,
Hussein's America-hating mother and his one citizen-parent, was only 18
at the time of Hussein's birth, Hussein could not possibly have been
born a US citizen had he been born abroad - which he well might have been.

The INA of 1952 describes who *is* a citizen at birth. If not in one of
the listed categories, a person is not a citizen at birth - end of story.
