It's not about the specific geopolitics of Ukraine/Russia/China/Israel/anything... it's about the unsustainability of the economic system.

The capitalist countries aren't turning back from immiserating their people. They're all-in on a model of massive wealth inequality, where the few own the houses, land, and other wealth, and the common man is in debt and is squeezed for rent. U.S. consumer confidence is at a 12-year low because the common man cannot afford things.

If people can't afford things but you want them to buy things, there is one capitalist solution: put them into consumer debt like credit-card-debt. But that's also maxed out, it can't be pushed further.

It's heading toward crisis. Pursing an unsustainable path is synonymous with heading towards a catastrophe.

The correct solution to this crisis is a leftist movement. But the left is disorganised and disempowered by oppression&propaganda. There's no left in capitalist countries, not an effective one.

(Same logic applies to the environmental crisis as well as the economic one.)

The welfare state was established by Clement Attlee after WW2 – an example of how a catastophe/worldwar can be the shock required to get the ruling class to come to their senses and change the economic system.

Something's gotta give, simply put. People have been pushed to the brink and it can't go on like this.

That implies some sort of crisis/catastrophic failure of the system. That doesn't have to necessarily be a world war, but it fits the bill, plus all of the pieces are in place with geopolitical tensions and militarisation.

The capitalist rulers can try to take/destroy China and Russia to fight the collapse of their wealth (I'm agnostic on the specific alliances). Destroying fixed capital with bombs is one way of resetting the hoarding of wealth.
