Scenario description
Assume U.S. forces keep NMESIS or a comparable ground-based anti-ship missile system on Yonaguni or another Japanese southwest island near Taiwan after the October exercise period, or they begin a follow-on deployment before the resolution date. The initiating change is an operational extension or renewed physical deployment of U.S. ground-based anti-ship missiles in Japan's southwest islands, not merely a statement that future deployments are under evaluation. Reported missile counts, exact basing duration, sustainment footprint, and Japanese support arrangements remain unspecified unless later sourced.
