I guess my comment was a bit vague. China is certainly currently interfering with our systems on a smaller scale. I was referring to a large scale, widespread cyber attack as described in the article.

It's highly likely China is capable of of that sort of attack. But I don't see how we're more at risk of that happening now than any other military action.

Another commenter described it well as another theater of a potential war, not necessarily that a war is imminent at this point
