I might agree with u in the past, but things have changed a lot since then. Frankly I don't see any favorable outcome like peaceful reunification for China in the foreseeable future, unless Taiwan economy collapse and chaos ensue. Taiwan economy still dependent on China, but they have been diversifying. I think we took it for granted that Taiwan economy will always depend on China.

The US is in a mission to sabotage China at every turn, and Taiwan is a big part of it. The US is using salami slicing tactics on Taiwan against China. This kind of visits will only increase in the future if China do not draw a redline. Not only by the US, but also by its allies. Before long, what seems like an aberration and a break from one China consensus, will become a normal thing. After that, it is only a matter of time before one China policy become one China one Taiwan policy. We have seen it in Lithuania recent move. Others might be tempted to do the same if there is no repercussions. More importantly, the US could learn from what happen in Ukraine, and send in massive weaponry to Taiwan. There have been talk about making Taiwan a porcupine, a fortress. If there is no redline drawn today, the US might even one day send in THAADS to Taiwan. It is better to draw a redline today, than sorry later.

As for readiness, if China could send in warships to Diaoyu, I can't see why we can't do the same with Taiwan. At least it is possible to send in warships close to the peripheral island coasts, just to send in a message.
