LOL.

There are a lot of ways around those fiber backbones. ie: there is an entire array of similar fiber paths around the world. No need to shoot a signal directly from NYC to LA when you can route through Europe - Russia - China and pop into LA via the Mexican cell system. There are also private satellites, WiFi links that can be stacked to jump hundreds of miles, digital cell connections, and good old fashion patching through on ham radio. Point being anyone wanting to limit information can slow it by controling the main fiber links but they can't, not without a huge amount of trouble, eliminate it entirely.

It also has to be pointed out that nobody is going to physically cut the lines. First, you may capture or control a resource but you do not destroy it. Cutting it automatically triggers work-arounds. Slowing it to a near stop is more effective because it backs up the system without destroying anything and forces the system to keep checking back.
