It's not about a single point of failure. It's about lots of different systems, each with their own unique set of vulnerabilities, and a well-resourced adversary picking them off one-by-one, escalating privilege, gaining persistence and then... doing nothing, because they're not at war... yet. It's like building up an arsenal of ICBMs without ever using them, but when they do get used, they're launched all at once.
