I think that's a crucial question. I'll try to answer as briefly as possible.
At the end of the day, it depends on what sort of contingency it is. I think China has learned a lot of lessons from Russia's war in Ukraine. If we expect an armada of Chinese ships to show up and do a full-scale invasion of the main island of Taiwan, I don't think that's how the contingency is going to play out. I think they are going to work in a "grey zone" and take a couple of islands around Taiwan first. I mention that because that's premised on the idea that they want to make it more difficult politically for the United States to make the decision to intervene.
I think a lot of it depends on the Chinese. If the Chinese engage in a full-scale assault on the main island of Taiwan, I think that the United States—I don't want to say they have no choice—is very likely to engage. If they pick off small islands like Kinmen Islands or Penghu Islands, it makes it a little more challenging for the United States to make that determination.
