I think it's important to recognize that some things in the world are inherently individual-centric and cross all arbitrary political boundaries and the Internet has become one. Even during the world wars postal service and telegraph service was maintained, notably with censorship imposed. We don't fight genocidal wars in large part; the people communicating with each other across battle lines will still be friends, family, or coworkers when the war is resolved. War has changed significantly with modern communication and there aren't many wartime secrets any more; troop movements and logistics are readily seen from satellites and aircraft. It's arguable that censoring communication between countries at war has no practical war benefit. As a sanction it is also arguably not effective because as an example North Korea enforces extreme Internet censorship and this hardship on North Korean citizens does not meaningfully weaken the regime. If anything, maintaining open communication to combat propaganda is likely the most beneficial approach. There's a video circulating of a captured Russian soldier in Ukraine face-timing his mother in Russia which would have been blocked by severing Russia from the Internet, to what end? Further isolating and estranging neighbors and family during a time of extreme stress? Finding common shared humanity is always more important than tactical warfare because it usually obviates the need for continued warfare.
