Very possible. And they’re probably rolling back now, as I see systems coming back up

The bigger day-to-day risk is selective censorship (deplatforming sites/apps, DNS blocks,..) rather than flipping a switch.

I'd advise you read the original ARPANET papers or something modern like Andrew Blum's Tubes to now more how this works.

- Emergency powers that could theoretically force ISPs to throttle or block traffic in a crisis (though never used that way domestically).

So it's not total control, but it's also not zero.

That said, the US does have significant influence in certain areas:

- Mandated lawful-access backdoors in telecom gear (CALEA) for wiretaps.
- Direct data feeds from big tech companies via programs like PRISM.

The core internet infrastructure is highly decentralized, no single 'kill switch' exists that the US government (or anyone) can flip to shut it all down. Routing is distributed, cables are owned globally, and it was literally designed to survive nuclear attacks.
