"Cutting one or a dozen cables simply causes traffic to get re-routed around the break. You'd have to cut them all. At that point, I'd think that someone in the government would notice link after undersea link going down and might become curious enough to investigate"

If 1/4 of the undersea cables were cut then Internet traffic would slow to a crawl. Trying to fix the cut cables in a hostile wartime environment wouldn't be that much fun either. Regarding taking out the satellites, I'm sure that there are laser systems to do the job. Satellites are too strategic and valuable to be left alone and unmolested.

In a wartime environment, the government would seize all of the remaining operative cable landing points and route mission critical data only. No more porn (except for the NSA...)

Satellites are also a security issue, but with SpaceX's StarLink LEO constellation, it's getting harder to cut that form of communications as well.
