would have liked to have seen them in Taiwan
Yes! So true. I suspect they are careful about where they park the B-2s due to design aspects they would rather not expose... same with all stealth technology. They were quite upset at losing that 'copter during the bin Laden raid, and I believe Pakistan sold at least some of the wreckage to China.
I have said for some time that one way to bring China to the table seriously would be to propose a nuclear Japan. China has a genetic historical fear of a militarized Japan. Since WWII Japan has depended on the US for its defense. Washington politics and foreign policy recently has to have caused anxiety in Japan.
