Answer 1

On top of redundant cabling others have mentioned, even if you managed to cut every single cable that goes into a country they would not be fully cut off from the internet(although their bandwidth would be miniscule by comparison). Satellite connections to the internet are available around the globe and, short of blowing up all comm satellites, impossible to block.
