Surely you get the internet in your hometown. Have you read about the two, major and expanding wars, with more potentially on the horizon, on top of the various skirmishes? Wha would the world look like if Harris were president in 2026? That is the question many forward thinking Europeans are asking.
Yes, I have internet in my hometown. Not the point.
The point is what you think the "current trajectory" means.
I have my own views, for you it might be that WW3 will break out tomorrow.
Here's what I think:
1) countries rise and fall. The US is falling. It's falling because America can't do anything now without it being a huge joke, Trump, Biden, Congress. The US has money, but that might change.
2) China is rising. It might not be that powerful, the current leadership is doing its best to keep power, and in doing so is destroying a lot of things that make the Chinese successful in business. However their GDP per capita is about $12,000 to $13,000 right now and I think they can double that easily before hitting the ceiling.
3) Russia is crazy. If Russia gets the Ukraine, it'll be poor. If it doesn't, it'll be poor. The war must be taking a toll and the rich are going to be paying for it and that'll cause loads of problems. However the future might be the ability to grow food and the Ukraine and Russia are huge exporters of grain. If Russia controls it all, it will cause problems for those not on the side of Russia.
4) Iran is being assertive. Backing Hamas, backing the Houthi, they helped destroy the US in Iraq, they can supply oil to China and other countries on the other side of the new Iron Curtain.
5) The population of China, Russia and Iran put together is HUGE (because of China). The population of NATO countries, Japan, South Korea etc is much less than the population of China.
So yes, we're moving towards a new cold war, the proxy wars are there, the Ukraine, Yemen, Palestine.... China might try and take Taiwan first then seek to dominate everywhere else, depends on who becomes leader in the next opportunity, or how soon they can take Taiwan, or if they can or not.
If the US moves away from NATO, the the Chinese, Russian, Iranian side will have it easy. With NATO it's not going to be easy.
