They don't care for a couple of reasons. The first is that it was already obvious to anyone who has worked with large-scale networks even before firing up traceroute. It was already widely known that North Korea has bad peering, because nobody but China wants to peer with them. The US is where most of the major cloud companies are headquartered (i.e. resources can be commandeered), and the defense budget would support an _enormous_ DDoS attack without even flinching. Secondly, denial of service attacks are worth much less to governments. They have the capability to physically break infrastructure either obviously with bombs or clandestinely via who knows what. They don't _need_ a DDoS to deny service, and it's certainly not their most effective way to cut off communications.
