This case would not be "99.9% of these cases." It is not quite the same as, for example, the attack on Sony. The main differences are: 1) attack targets intelligence, rather than IP 2) target is US government, rather than private sector company 3) attack targets government infrastructure, rather than corporate infrastructure. I think that in this case the US likely has more resources at its disposal for analyzing the attack than, for example, it could use after the Sony attack, so a quick response is predictable. I also see no reason to doubt China as a possible culprit, as they certainly have both the capability and motivation for this attack.
