We know what a world dominated by Xi-Putin means.
•Crackdown on democracy movements (like in Belarus, Hong Kong and Kazakhstan).
•Territorial expansion (starting with Ukraine and Taiwan).
•Attempts to destabilize and overthrow democracy (Russian interference in elections, Beijing's "united front" strategy, disinformation etc.).
When people blame the US for confronting Xi's regime (not "China"!) they're either clueless or useful tools

Btw, I was against the Iraq war and US-UK regime change policy. I was yelled at by lots of people, even liberals, over the years.
During the Arab spring, e.g., it wasn't fashionable to say that the US and Europe should stay out of it. There was huge animosity in those debates.
But the mistakes of the US and its allies are no excuse for supporting dictatorial regimes, not at all.
