Bosnia was about to be destroyed and more recently, attempted to be divided by neighbors and they're still fine.
Look at anywhere that's not Americas or Western Europe.
It is debatable whether Bosnia is fine or will be fine. It is in danger of new rounds of violence. For that matter, even if Ukraine wins, which I hope, it wont be fine. Wars do actually damage places where it all happens and price is paid for many years after.
Part of the strength of the nation, however, is that everything is a big deal, all the time. This causes things to (eventually) get dealt with.
Residential structures are made from ever lower quality materials that are thinner than ever and with shorter lifespan (accelerated aging, necessitating sooner replacement).
Foods are being stuffed with ever larger quantities of fillers such as corn, high fructose corn syrup, sugar, and air to make the package look big even though there is nearly nothing nutritious inside.
It's a mirage.
It's true that the US has a lot going for it. No enemies to its north or south, still the largest economy, high levels of education, etc. At the same time, standards of living have seen a large drop over the last two years. This appears to be intensifying the arguments over social issues, and increasing incitement to violence. What I see when I look at places that are not the Americas or Western Europe is that the peace and wealth people take for granted can be lost so easily.
As an American, allow me to be even more inflammatory. Americans think that everything is falling apart because we've collectively never had a real problem in our life.
The amazing thing is as an American, I can ignore TV, all sources of news, fights on Facebook, etc. I've done it for years. Nothing bad happens. In fact the only effect is that I am blissfully unaware of all the minutia that are leading people to believe everything is falling apart.
Most people are still alive and life goes on but it is not a road you want to go down if you can avoid it.
