We have to remember that policy discussion papers that are not ultimately adopted by a  Government are routinely prepared.

That said, it is deeply unsettling that the new Trump Administration may be considering such an option in its current state of incoherence and disarray and given the incendiary, deeply divisive and probably illegal nature of such a policy.

Seriously discussing (if that, in fact, is happening) let alone adopting such a policy would be the equivalent to throwing gas on a burning building.
