May I briefly add something on the increased defence spending by Japan?
If this had come out five years ago, there would have been great political opposition within Japan. Japan, as you said, still remains at its heart a pacifist nation. There would have been a great deal of public opposition. This has not been the case. The only opposition we're hearing is, “How is Japan going to afford it?”, meaning the Japanese voters themselves are very much aware of the dangerous neighbourhood they live in and the risks not only from North Korea but also from China.
Also, we haven't talked about this yet, but there's an increasingly reluctant United States to be a permanent Pacific power. It's hedging against those realities.
On the issue of Taiwan, I am of the camp that China is not preparing for any attack on Taiwan, but there are possibilities of miscalculation. They have intensified surveillance by sea and air. The possibility of things going wrong and triggering an unintended consequence as a result is something that keeps me up at night, as it does the Japanese leadership.
