Surely you don't expect the WP article to list every act that might be compatible with the idea of a "cold war"... I feel you are trolling a bit. Sabotage is still a plausibly deniable act--contrasted with, say, rolling a tank across one's adversary's border.

Stuxnet is a weapon of sabotage, it is fairly direct, and yet it is not the same as an open declaration of war.

I can't believe the level of dishonesty here. The point is obvious: NONE of the acts cited by the WP article were acts of violence.

Did you miss out on Sesame Street? "One of these things are not like the other..."

No I'm not trolling. I am expected to be treated like a troll by the herd here however.
