> I doubt Russia can keep this one going for a decade.

They only need to keep going longer than their opponent. Ukraine has fewer soldiers and resources than Russia and currently has almost no offensive capability, as seen on the battlefield. All they can really do is defend, and even then they’re still losing ground, not much, but still losing territory. Here in the West, we’re facing economic problems, high debt, and a shortage of weapons production, especially in the EU. I’d like what you’re saying to happen, but that’s wishful thinking. And Afghanistan wasn’t the primary or even a major reason for the Soviet Union’s collapse.

> I doubt Russia can keep this one going for a decade

They have oil, gas, and minerals that the rest of the world needs, and they have an internal propaganda machine that lets them hold out for a long time. I remember "experts" saying Russia would collapse economically in 2023, then in 2024 for sure, and that they’d run out of rockets. Now it’s 2025, and that collapse isn’t even on the horizon.

Fair enough there hasn't been much economic collapse yet but we shall see.

> Ukraine has fewer soldiers and resources than Russia and currently has almost no offensive capability

No offensive capabilities and yet russian refineries keep burning reducing its capability to produce fuel to the point that the fuel in Russia is most expensive it has ever been by a large margin. No vehicles run on crude and russia will eventually have to walk their soldiers to the front lines.

Experts weren't necessarily wrong. It's just hard to notice collapse of something that's already almost a failed state that constantly lies about how things are.
