GigaChat is russo-centric and is completely useless outside Russia itself, performs absolutely worse than Mistral once you start using English. Reminder that Russia's economy is smaller than Italy's alone. They are not winning over Europe in any single metric, let alone against the poorest country in Europe, which is not even part of NATO nor the EU, on the battlefield.
I've heard that before though. I don't think you can compare economies like that since Russia has "near infinite potential" in natural resources, people, etc which Italy doesn't.
They can kick into a true war economy and then become significantly more of a threat. They haven't done so yet because the middle-class population likes their luxury lifestyle (for now).
I highly doubt Ukraine will "win" - in fact I believe Russia is ramping up to find an excuse at some point to attack a NATO country, but in a way and during a point in time it's difficult for NATO to retaliate.
