Kinda doubt it would take a full day.
If the Russians launch a nuke, every nuclear state is going to get automatic warnings that either an ICBM has launched, or a nuclear flash was detected. A few minutes after that, the US president gets forcibly dragged to a bunker under the White House and told to pick a nuclear response and give the launch codes to Strategic Command.
If the president elects for ICBMs in his response, then those launch within a minute or 2 of the order going out. Russia will see this via satellite and will probably also launch in retaliation. In about 30 minutes, hundreds of nukes are in the air or detonating, and probably dozens of sub launched nukes have already gone off. A few hours after all that, the nuclear bombers arrive and drop their payloads. Nuclear war, the whole thing from start to finish, takes less than a business day. Nukes destroy cities and decapitate governments in one strike, so the proportional response is extreme violence until the other party stops launching or everyone is dead.
And that’s really just the US and Russia, there’s like 10 other nuclear nations that will also pick a side. If Russia fires off a nuke, someone will respond in kind, and that just leads to the rest of the dominos falling.
My point is, nuclear war happens so fast that there’s not really time for china to say anything. Once you light the fuse, it doesn’t stop. No one has ever tried to restore deterrence, because no one was supposed to be stupid enough to test deterrence. The plan for restoring deterrence is therefore equally stupid: keep launching like we planned to anyway.
200miles/8hours of skating straight means an average speed of 25 miles an hour.
Ambitious, considering the average speed of a skateboarder is closer to 10 miles an hour, but it could be possible if he was extremely fit, had unbreakable bones, and the US was a flat plane for 3000 miles like this guy thought.
