TOKYO -- The global geopolitical order has transformed in the year since Moscow's invasion of Ukraine, prompting Japan and the U.S. to update their alliance to confront rising threats from nuclear-armed China, North Korea and Russia.
A model for upgraded cooperation can be found at the Tokyo-area Yokota Air Base. A 30-member information analysis team began operating last fall, uniting personnel from Japan's Self-Defense Forces and the American military.
