[0] Is I have to say simply wrong on every point.

Russia has large missile defense deployments S400 and S500 and selling them to lots of countries. This is in no way a secret and a huge bone of contention between Turkey and the US for their purchase of S400.

Hypersonic missiles make aircraft carriers sitting ducks without any defense. This is a pretty damn large shift in military power at the US expense.

For hypersonic missiles to work against ships, they require either nukes - in which case conventional ICBMs on a lower trajectory work fine - or terminal guidance, which is an absolute bitch through 3000K plasma. There's a difference between being maneuverable and maneuvering to hit a moving target, after all.

I don't think they change the naval balance of power much.

[0] is exclusively concerned with the balance of nuclear deterrence - it's the Bulletin of the Atomic Scientists after all. What they mean with missile defense is defense against strategic nuclear weapons.
