Final paragraph of one of two Stuxnet articles in the latest issue of The Economist (the other article is A worm in the centrifuge)
Stuxnet may have failed to do the damage its designers intended, but it has succeeded in undermining the widespread assumption that the West would be the victim rather than the progenitor of a cyber-attack. It has also illustrated the murkiness of this sort of warfare. It is rarely clear who is attacking whom. It is hard to tell whether a strike has been successful, or indeed has happened at all. This, it seems, is what cyberwar looks like. Get used to it.
