It's pretty hard to believe that the PRC would actually go kinetic over a Pelosi visit, but more aggressive incursions into Taiwan's ADIZ is more plausible (and mentioned in the CNN report). Or perhaps something like an actual overflight of Kinmen daring Taiwan to take a shot. All the leaks on the US side have made this unnecessarily complicated, but at this point, I think the best solution is for the visit to happen, but in a subdued and low key manor.
