This is not about Taiwan in specific, but when we sell something, that means we don't have it anymore. We can get it in the future, but we don't have it now. … [A]nytime we do any sales, not to Taiwan, to anybody, it is always balanced against what are our own needs in different parts of the world, and whether we can afford to sell something because we may need it for ourselves. … The relationship between the United States and China will define the 21st century. The idea that we would not interact with them at the highest level is irresponsible. It's outrageous. We have to.
