Re: is it really surprising?
"Western defence strategies have for a long time been based on having the shit-hottest offensive capability. Just to be sure the rest of the world gets the point, thelatest weaponry is used when convenient conflicts arise, either directly or by an ally."
What military strategy have you been reading, then? The feeling for over a century and the numbers have always favoured the defence. [Non-German] Strategists exploring the concept of Blitzkrieg warfare even went so far as understating its presumed effects in the interwar period, so as to not to be seen as provocative. I don't recall any real NATO capability to roll through East Germany back in the 80s, either.
And if anything, the latest wars are an excuse to use all the old stuff before the 'best before' date runs out. The bleeding edge straight-outta-the-box stuff gets used very secretly and over-cautiously, lest it fall into the wrong hands. It's seen as more effective as a secret and unused weapon than a public and tested one.
"It seems to me that the same holds true for cyberspace."
That's kinda guesswork. Governmentally-wise the US started keeping all of its sensitive systems firmly off-line a long time before they really started thinking about getting serious on offensive capabilities.
