War scenario - Networking world.

How will the networking world e rocked if there will be a war between the US and China?

Let's take 3 scenarios:

1. Conventional war:
The US attacks China, China strikes back, mass DDoS attacks between both countries, they throw all the conventional weapons on. The USA wins by a large margin due to superior military power.

2. Mild Nuclear war.
The US attacks China, they both throw a nuke, they have peace after they see the damage done. China will lose more infrastructure due to American Superiority in terms of military power.

3. All-in annihilation.
Full nuclear war, both countries deplete the nuke stock. Both countries go into the stone age from an industrial point of view.
