awww... now I want to see it...
Hooo boy... if Corona makes it over, even if it isn't in ConUS, it might the be the mouse that sinks the boat. At least the lack of trade should help slow it down.
For a minute or so, I had another sentence higher up about nobody really noticing the December 31st report in China about people dying of an unknown respiratory virus, but... from what poking around I did, I couldn't find anything about any real international concern or reports of it until early January...that December 31 report was
in China, which.. North American News Media probably wouldn't have really seen, and leaving that sentence out made for a more dramatic
final sentence. So I went back and yanked that sentence.
Pair that together with current best guesses that the earliest Covid death in the US was as stated in the snippet, and was from community spread...that hints that it was probably present and spreading (if
barely) by the turn of the year. And yeah, Covid on top of the panic and incompetence and...?
I would expect we would still see significant spread in North American continent. There would still be trade across the various North American borders - it would be even more important, with the rest of the world no longer available - and while there wouldn't be as much international travel (there being far less nationals to inter), I would expect there would still be significant travel in what was left. Probably even more travel than normal between the remaining countries in the name of coordination and trying to pick up the pieces and get ahead and so forth.
Just to make things even more "fun", even when Covid gets
noticed in this suggested timeline, there's not much that can be
done about it. Consider: no imports of raw or finished goods means that even basic PPE is
far harder to acquire than OTL. On top of that, if there's any chance of staving off a total collapse, then a
lot of manual labor is necessary. North America would
very badly need factories to tool up before things totally crashed, and would
very badly need those factories manned. That would mean a lot of people
needing to work in close quarters.
And a lot of people dying.
The casualty rate could easily jump to what we saw in Italy - 7+%, wasn't it? Or even higher. And even so, it would be
necessary to tool up or the death toll would be even higher. OTL, we're relying on a lot of imports...but in this scenario that wouldn't be possible. Add to that the Republican insistence that people should be proud to sacrifice themselves to Covid even OTL where it's not necessary, and their apparent desire to see more and more people die and... yeah.
Lots of bodies.
I'm not sure how that would play out, but it would put a
lot of stressors into place, and I would expect current society to
shatter in some way. How? I have no idea. Riots in the streets going after Republican politicians for murder? Maybe. Grim acceptance of death and bodies rotting in the streets? Also maybe. Panic and riots and complete chaos? Seems possible to me. But whichever case, if 5-10% of the population keeled over to a pandemic
as things were crashing because of the ISoT? I can't imagine "stability" would be an outcome - especially not with the idiots in charge. And that makes it a lot harder to do any sort of longer term prediction.
I wouldn't be surprised if Christopher Columbus sailed over in 1492 to...well. Probably not the "Indians" (not actually India, dude) from OTL, but to some fragmentary leftover primitives with vague legends of the gods and peoples of the past. Maybe the occasional artifact, but probably not - we don't build to last thirty thousand years - we use stuff that
rots and rusts.
Any sort of long term societal survival would rely on the weather and enough technology remaining to keep high tech farms running, and between the total incompetence of the US leadership, the panic and rioting caused by the uncertainties
exacerbated by said incompetence, the lack of ability to import machinery, the lack of capability to
produce machinery... farming could have serious trouble producing enough food. The seed problems other posters have mentioned wouldn't help either.
So you end up with major food shortages. Armed gangs protecting their food. Armed gangs being perfectly willing to kill to eat, and probably killing the people who know how to farm and destroying their equipment while doing so. America has a
stupid amount of guns. Get a lot of stupid people a stupid number of guns and a lot of panic, and... well.
Canada and Mexico would have problems, too, I assume - I would expect a 5-10 deg cooler climate to
smash food production. Maybe
something could grow everywhere, but would the same things grow? Things the locals knew how to grow and had seed stock for? Would anything grow in the places where the farms existed? What would happen to weather patterns with the world of 30k years ago compared to the weather patterns of today?
Maybe some fragments would survive and rebuild, but... I'd be shocked if there was anything recognizable after.
