“There is nothing new about the Russian-Chinese alliance. They have been doing war games together aimed at us since 1991.”
China and Russia are more likely to go to war with each other than they are with the USA and NATO.
Last month the Chinese moved a bunch of troops into Heilongjiang putting them into position where they could easily invade and annex the Russian Far East (RFE).
If Russia invades Ukraine and gets bogged down there I fully expect the Chinese to invade the RFE. Why? Because while Russia will get slammed with trade embargoes by the West no one in the West will GAF if China does to Russia what Russia does to Ukraine.
To the contrary, the West will be relieved that China is not invading Taiwan.
A Russian Chinese war would be a conflict between the world's two best militaries. Russia has successfully defended against Western invasions under Charles XII, Napoleon, and Hitler, but was overrun by the Mongols, who invaded from the east. In modern times, Russia lost a war with Japan in 1906, but defeated them in the 1939 Manchurian Mongolian border war.
Such an event would save the United States from their machinations. But I’ve never seen any evidence that you could be right and the defector literature all say the opposite: all alleged disagreements between Russia and China are generally stafed for western consumption and that the two countries will always be united in killing us.
