While recent media reports may have painted this news in a glorious form, the truth is that Washington has neither shifted focus away from Russia nor changed its views of China. While China has certainly bolstered its nuclear capabilities and aims to continue doing so, this information, and America's strategy towards it, has been public since 2022.
The US is setting the stage for yet another unnecessary war. Top US military officials have even alluded to this publicly, making arrogant claims about how they would win should China ever invade Taiwan. While these remarks may be fun for America's top brass, their real-world consequences will be catastrophic for the rest of the world.
There's a 10% chance that there will be a US-China war before 2035, according to the Metaculus prediction community.
