I agree that they oppose US hegemony, since they want global power for themselves, but they're starting to pick up on how China can't really be appeased forever. They spent years trying to work with China to access their markets, knowing full well that if they didn't serve China's interests, China would just steal their IP and freeze them out. Now, even though they've fed the crocodile the whole time,
it's starting to eat them. This is what changes things. They were in denial about Xi and his neo-Maoist nature for nearly a decade, and they hated Trump for rocking the boat, thinking that they still had time to return things back to the old status quo.
Now that Biden is in, and things are heating up rather than cooling down, they're starting to get their heads right. They can't function in a world without US hegemony. There is no reign in hell option. Only suffer in hell or serve in heaven. So they're going to come around on this "death to Amerikkka" tard shit. That's where the Trump Redemption Arc comes in.
