re: My take is that Russia and China have gotten together in secret and will attack

There have been reports that Russian officials have stated that an agreement/understanding is in place between Russia and China that if Ukraine attacks the Donbass or if large numbers of NATO troops are stationed in Ukraine or if the US places a missile system there (similar to the ones in Poland and Romania), Russia will invade and China will attack Taiwan. Also that if Taiwan declares independence, China attacks and Russia invades Ukraine at the same time. Russian officials have stated/told other officials this publicly. Is it true, who knows? But Russia and China have formed a defacto alliance and held military exercises together last summer in China. They are sharing/cross training on military technology also.

When you start seeing Chicom troops holding military exercises with Russians on Europe's/Nato's border many of the Eastern NATO member countries are going to shite a brick.
