Russia and China:

The US was still vigilant though, as they knew that even though surveillance had been increased in China, China could still make a move, which the US was at this point kind of hoping for, thing was that their propaganda campaign went well, a little too well, to the point that people were beginning to ask for war despite not having a solid enough reason for doing so.

At the end of the day, despite how much the US wanted to get rid of the two Communist counties known as Russia and China, They couldn't do so based on pure suspicion that they were planning to do something. As that would not only hurt its reputation but would also make it so that the war receive less support from neutral countries if China or Russia ended up doing nothing.

As for how the UN was dealing with the whole situation, they just weren't, the UN had always existed with the purpose of stopping countries from going to war, and despite the fact that they did have a military of sorts, the system worked purely because of the belief that the UN could stop wars, as it really couldn't.

So with now three wars breaking out consecutively, the Un had become a joke internationally and was no longer seen to hold any power, after all as mentioned before, the system only worked because people believed that it worked, so now that they realized that it didn't, the system just collapsed in on itself.

As for China, it was planning something much bigger than avenging their fallen ally, despite how things looked on the surface, China actually had a serious lack of people that could serve in the military, thing was that Communism, both in the former Soviet Union and in China was very effective in lowering the birth rate of it citizens.

This is something that is very easy to see as long as you check the population pyramids of both China and Russia, Communism leads to rapid industrialization, which in turn leads to people having fewer children, as that's what happens when a country becomes more advanced. A basic rule of thumb, if a country's quality of life improves, its population will decline.

The thing that people don't really talk about when it comes to Communism is the fact that both China and the Soviet Union weren't technically Communist, and were in fact just an extreme version of Authoritarian socialism, since for true communism to be achieved, there would exist no countries, that's why the ideals of communism are so appealing, but the results are so different.

It's because the system these countries were ruled with, was actually more authoritarian than communist, basically using the ideals of Communism to convince their populous, while ruling through Authoritarianism, with a prime example being the rule of Stalin. Since he just did whatever he wanted while telling the people that it was a requirement if the Soviet Union was to flourish under Communism.

That was also the biggest flaw of Authoritarian socialism, by ruling with an Iron fist, the dictator of an Authoritarian socialist country got to do whatever they wanted without being told no because those beneath them feared that they would be killed if they opposed or even dared to not immediately agree to their 'great supreme leaders' ideas.

Therefore making it so that the dictator of an Authoritarian socialist country only had 'yes men' as advisors, basically, people that will always agree with whatever they say, and since no human being knows everything, eventually that countries 'great supreme leader' eventually makes a terrible mistake that nobody stops him/her from making.

A prime example once again being the rule of Stalin, where he made terrible decisions like creating the GULAG system, Collectivization, causing a famine, the great purge, Order No.227 (defending Stalingrad purely because it was named after him), punishing prisoners of war (because they were 'traitors to the moterland'), ignoring war crimes… the list goes on, I think you get the idea.

Point is that both China and Russia were in desperate need of more people that they could use as soldiers to remain influential countries in order to continue expanding the ideas of communism (at least when it came to China). And the best way to do that without leaving their communist roots was to invade other countries.

China used this fact to convince Russia to take over the northern part of central Asia. Although China did want control over central Asia in its entirety, they knew that it was their biggest bargaining chip right now, plus, their main target was still India, so they were willing to give northern central Asia up to Russia in exchange for a cover against US media.

As for Russia, it accepted the deal because it was already in hot water with the US, and knowing that propaganda had started to spread again, it knew that it was only a matter of time before they declared war, therefore, having more soldiers was a perfect deal to them, especially since those new troops could be sent to Ukraine after minimal amounts of training.

As planned, although China was beginning to become the center of attention, thanks to Russia's sudden movement, the spotlight was shifted almost immediately, and although the US government did try to get some media outlets to still cover China, almost none were willing to, as this kind of thing was basically a gold mine for them.

Just like that, China was able to go under the radar and take a little more than it said it would while the American populous was too distracted over Russia's major movement, it also sparked slight internal conflict in the US as it was basically common knowledge that there were US officials with close ties to Russia.

And although it wasn't the way that the US government had planned for things to go down, they were still given the perfect opportunity to get rid of one of the two communist powers. What they didn't know was that they were doing things exactly as China wanted, for things going this way was the only chance China had to actually win a war against the US.
