The exercises around Taiwan normalize this level of military presence, just like frequent flyovers into Taiwan airspace normalized those flyovers until Taiwan didn't bother scrambling jets anymore.
PR flop is just that, a PR flop. Domestic audience is managed via censorship and non-stop messaging shifting the narrative, whilst any overseas impact disappears after 3 days anyway. The permanent change is the normalization of increased military presence.
On the US side, this visit did not allay any one of their internal problems, so the more time passes, the more I see this as a worthwhile trade - US gains a rapidly dissipating gas, while China takes another small step forward.
To be honest, there's far less Western media coverage of this than I expected, so it looks like their trigger point for a mass media campaign (China fires first shot) didn't come to pass.
The longer China can kick the can down the road without a war, the better for China and the less advantageous for the US, and thankfully cool heads prevailed last night.
