Just because it’s not mechanically automatic, does not mean it’s not a launch on warning system.

The key phrase there is “it does not rely on a launch-under-attack policy to ensure credible defense”

If the US detects a ICBM launch, it will launch a response. It does not matter if the thing that presses the button is a person or an automated program.

Launch on warning just means a country won’t physically absorb a nuclear strike before launching, but will launch if an enemy launch is detected. It has nothing to do with automatic launch systems.

You know the US also has a launch on wanting policy.

If any of the billion dollar spy satellites see an ICBM launch that’s even vaguely going towards the US, we launch an overwhelming response.

Russia isn’t going to drop a few nukes and waltz away, because the US has the same system or better in place already. Especially if Russia hits a nato country, we’re all gonna die due to MAD. One bomb breaks MAD.
