For Taiwan, when we look at this, we know how the Chinese leaders, Chinese academia or military generals discuss the prospect of unification. Let me elaborate.
The Chinese vision of unification with Taiwan is a picture of a stronger China, a China that they call the rejuvenation of a great power. If and when they know that this unification is going to be at their great expense, they won't be ready to do that, and all the more if we let them know that indeed it's going to be very costly for them.
For Chinese leaders, unification is a way to make China greater, not weaker. Right now the whole world is telling Chinese leaders that if they use force against Taiwan, they are not going to get a stronger China after unification, so that is not what they are pursuing.
You've heard a lot about what we say in Taiwan, why we have confidence. This is one thing we are confident about. Of course, you can argue that a dictator may think about things in an irrational way. If that is the case, it's difficult to carry on a very reasonable discussion, but I am telling you that right now we don't see an invasion from China as an imminent threat.
