The US is in a desperate economic state. They are not earning enough to pay their own bills.
It is not sustainable, according to anyone.
Nobody knows what's going to happen, but it's going to be bad, though "printing money" will last for a while.
If foreign countries (eg China) stop buying US debt, it looks like the US dollar and the world economic system collapses. (Hence Bitcoin, for whatever good it may do.)
Spending in Ukraine is definitely high enough to concern even the Democrats. Russia will take all of Ukraine.
The US people have bigger worries than Taiwan - it doesn't matter much. They make chips which currently can't be made elsewhere but everyone (including Eire) is building new fab plants. Except the UK.
If Taiwan resists China, they'll get blown up.
Russia is doing rather well, despite the isolations from the world economies. Their Oil still flows and the west just buys it a different way. They're fairly self-sufficient, even if at a crappy level which starves some of the population. Putin has far more control of his country than the US gov does of the US, so no civil war.
Trump just makes the US situation a bit more unpredictable.
Wherever I look, I see global tipping points. It's just a matter of which one goes first.
Wars, food, water, warming, disease, people like me earning from a laptop and not needing to work, and then telling everyone else how, so nothing gets done.
Learn Russian, Mandarin and how to grow veg under a cloud. Then you might be ok, until there's massive destruction. I give the world 10% chance of getting to 2100 without that damage. I wouldn't be surprised if it's within 20 years.
