"on April 2, the command conducted the "Strait Thunder-2025A" drills in the central and southern waters of the Taiwan Strait" [Strait Thunder-2025A]
The named military exercise, timed directly after Taiwan's hostile-force designation, is concrete evidence of the action-reaction escalation mechanism the signal describes.
Reasoning from this article
The article traces a clear causal chain: Taiwan's National Security Meeting → hostile-force designation → PLA military drills, with civilian deportation cases serving as the proximate trigger for the political escalation. This is a textbook security dilemma spiral where defensive legal and administrative moves (Anti-Infiltration Act enforcement, residency revocations) generate military responses that then justify further defensive measures. The article notes this occurs against the backdrop of U.S.-China relations 'at their most volatile in decades,' suggesting the local spiral is embedded in a larger structural deterioration that amplifies each local incident.
