I think the place where Germany ended up currently is largely related to this disconnect from reality.
China is out of this group. It's friendly with Russia, but countries are not allies, as there are no obligations.
That's pure hopium from the west that China would against her own interests not help Russia if Russia faced an existential threat.
Also there are hard coded defensive obligations, an attack on China would be considered an attack on Korea, which further has a MDT with Russia.
It is not a direct "pact" like the ww2 axis or Central powers where you had countries deciding they should overtly marshal troops together in peacetime (that's NATO), rather you have a looser coalition of countries bound by a network of MDTs. Which is exactly the same setup as the Allies in ww2. This still 100% fits the standard definition of a military alliance.
China is an ally to DPRK, and sustains it out of obvious strategic necessity. But it is not especially friendly.
DPRK is quite suspicious of China, and Beijing is quite ... discontent with Pyongyang behaviour.
This is nonsense, DPRK is a complete puppet state.
NK to Iran are partners, but no more; their defensive link is Russia.
Otherwise, there is no way no particular reason one can help another.
Iran is not part of the alliance, it's just a major partner. I don't think anyone can claim China considers Iran an ally since Beijing much prefers to work on all middle eastern countries at once.
What may look like a web of connections is really failed blitz to collapse Russia onto its own adventure, which backfired to historical proportions, and forced Moscow to look away from the west for at least a while(Russia noticed that Asia exists). Otherwise, there are few interconections in this group.
Moreover, the group is sorta weird: Russia has some program(mostly spite), but doesn't have enough weight for leadership; neither it really likes where it is currently. China has weight, but doesn't have program (or desire) to claim leadership. Especially in this group, which will come at the expense of western markets.
An alliance doesn't need a clear cut leader. Ww2 allies had initially as majors for example Britain, China, France, Poland, then the USSR. Many of them didn't have direct MDT, and until USSR started picking up speed, it would really be impossible to say which country should be "leader".
And the alliance still worked fine.
Beijing power vertical(红士大夫) has thousands of years of historical heritage - north is just too important to alienate. But otherwise, chinese literati and business circles would happily exchange Moscow for Europe and US.
You're falling for the good cop bad cop routine used to fleece the enemy before the real fighting begins. All good scams begin by offering the victim something that is too good to be true. Listen to yourself, do you seriously think China would happily exchange it's own northern bulwark and resource safety for what, to worship hostile EU/US? How does that benefit China?
In 2022, Beijing trapped Europe into thinking it wouldn't carry Russia, so they rushed their economies and supplies into Ukraine, only to face a Russia with infinite funding due to China, which devastated their economies and effectively put EU off the board.
In 2025, the new trap is Russia feigning that they won't support China. If US accepts a deal from Russia, it will bust EU US ties. It might even let Russia go on another conquest in Europe.
It is just realpolitik. Nobody is waiting to serve the west any free lunches like so many westerners are hoping for. This hopium is what leads them to get battered over and over.
