The war that would follow would be a trench conflict
What?
Everybody that writes about this potential war, lays out roughly the same scenario:
1) Cutting of subsea cables
2) Disabling of satellites in near Earth orbit
3) Cyber attacks on key infrastructure
4) Kinetic strikes on forward basing areas
The world economy, and the world's stock markets - would collapse on Day 2 of this war.
Don't think you can predict so easily what shape it will take. It will likely be unlike any war in our history as a species.
