This week on Talk Nation Radio: the poisoning of the Pacific and who the worst culprit is. Joining us from Tokyo is Jon Mitchell, a British journalist and author based in Japan. In 2015, he was awarded the Foreign Correspondents’ Club of Japan's Freedom of the Press Lifetime Achievement Award for his investigations into human rights issues on Okinawa. His latest book, Poisoning the Pacific, reveals the environmental damage caused by decades of U.S. military operations.
