Nuked out of existence?

Hypothetically it is possible for nobody to win with nuclear spoils. Very appropriate, I know.
Imagine a particularly savage game, probably more than a few players and the nuclear cards go off everywhere.
A situation could arise where there are but two players left with a minimal number of regions and a player must use their cards, due to their number.
However, their nukes both destroy their opponent's and their own regions.
Nobody wins.
(I am sure this must have been raised before, it's just my google-fu is failing me).
