I think the 'Trump solution' (No legal basis but an ad hoc approach to practically everything) will not obtain in the case of the American 'Jihadi Bride'. I've run into a Saudi professional, lives full time in Arabia, full blown Wahhabi but by virtue of being born in the U.S. a legal American citizen. I don't think that can be changed without a Constitutional amendment. By now I'm sure we are all aware of services that provide for foreign women to visit the United States on what I believe is a tourist visa and give birth in the United States. Haven't heard the Current Occupant opine on this matter.

Meanwhile there are plenty of legal ways to intercept and arrange protection from and for Jihadi Bride. The American Way would be to arrange an appearance on "Love Boat". Since that is not running anymore we can probably do a stand in on Law and Order. Or NCIS DC.
