The internet is literally designed to survive WWIII. Your concerns about the US infrastructure is not incorrect but a management issue, not a technical one. In case of large scale BGP attacks much will go down but big ISP's like google will simply drop all non rpki routes and naughty neighbours & continue life per usual. Perhaps such a attack should happen as this would force everyone to have their shit in order resulting in the likes of you having peace of mind instead of valid concerns.

The internet is NOT designed to survive a war, that's a urban myth. The first thing that would happen in such an event would be the deployment of the stash of Zero day exploits that every major power has saved up for the occasion.

December 7, 1941 was a peaceful Sunday, until it wasn't.

February 26, 1993 was just another Friday, until it wasn't.

September 11, 2001 was just another Tuesday, until it wasn't.

I was only a bit worried, but these type of events have a non-zero probability.

That would be yet another MAD scenario, so that's not going to happen. ( And black swan events always can ) https://en.wikipedia.org/wiki/Mutual_assured_destruction
