> It's mission was to destroy some expensive industrial centrifuges and set back Iran's nuclear program. And it destroyed some centrifuges precisely as it was designed to. At that point discovery is inevitable, but whatevs because "mission accomplished".

I think it might be considered a partial success, but mostly failure. It did successfully set back Iran's nuclear program and destroy some centrifuges, but it spread too widely so it was probably detected much more quickly than desired.

Also, if it had been discovered only at the nuclear fuel plant, Iran might have kept quiet about it out of embarrassment, allowing it to be deployed elsewhere. Instead it was picked up by a major AV vendor and dissected very publicly.
