It would have been quite the win if it had caused a meltdown. That might have delayed the US nuclear attack on Nagasaki. Although perhaps enough plutonium had been produced by then.
As I understand it, Japan didn't surrender until Nagasaki got nuked. And maybe Russia would have invaded before the US managed it.
They had quite the grudge over Leningrad.
Find this ironically interesting. The same goes for almost every new cyber attacks out there.
It does? Back when the press mostly meant a few big companies in your own country it was easier to suppress info. Now for example the US government might be able to ask CNN/Fox/NYT etc but they can't likely ask the BBC or Al Jazeera or the 1000s of news sites, bloggers, tweeters, facebookers.
