China and Russia's Non-Interventionist Stance
China and Russia will not fight for Iran, bro. Never. I don't even think Russia and China will fight for each other. If you look at China for the last 50 years, bro, it's all self-defense, self-containment. They're not adventurous like that. Look at Taiwan as an example. They could easily take that over. There's a reason why they're not really doing that. They don't want to take it too far.
Historical Precedent
Even going back to the Qing dynasty and the Ming and all these dynasties, they're not really expansionist. The Chinese are not really expansionist like that, let alone would fight for some other country. When was the last time China ever fought for another country?
Potential Support
What is possible, though, what is conceivable, is that they would give material and economic support to Iran, like what they did with Pakistan against India. That's a very high possibility. So they're going to give them, you know, whatever it is they need, planes and stuff.
Russia's Current Capabilities
But I don't think China is going to, and Russia is kind of drained from their fatigue from the fighting with Ukraine, bro. So I don't think they even have the capabilities for it at the moment.
