The ambiguity is still a valuable deterrent, and avoids the diplomatic cost of violating the NPT in peacetime, etc. That cost would doubtlessly be less if the violator was presently facing an existential threat.

IIRC, Israel follows this strategy. Everyone knows they have nukes but they've never confirmed it.
