> over some computer hacking and internet trolling?

No, no, "some computer hacking" (because who would worry about not being able to watch funny cat videos for a while? it's not like people do anything important using computers...) won't do much. But the next Stuxnet targeted at Russian infrastructure could well spell the end of us all. Honestly, I'd be quite content in that situation - witnessing, for however short before dying to radiation, the literal end of history (instead of the pseudo-one from the '90s) could be strangely rewarding.
