One of the theme's of last week's show was a Japanese peace garden but the garden that the viewer saw was clearly Chinese, the reference to koi notwithstanding. For a show about America's foreign policy, you'd think someone on the staff would do some basic research as to what constitutes a Japanese versus a Chinese-style garden. Granted that there are overlaps (and the production of Japanese gardens was definitely influenced by Chinese gardens), but the architectural screens and the rock formations were decidedly Chinese in inspiration.
