Lt. Cmdr. Elliot Rothrock of Joint Detachment Sheridan stated that "defense planners are no longer talking about hypothetical scenarios. We are working from timelines that could require mobilizing 50,000 reserve sailors in 30 days," regarding American planning for a war with China over Taiwan, according to an X post by @__CJohnston__ published over the past hour during the reporting window ending 4:16 PM UTC on December 30, 2025. This disclosure occurs on Day 2 of China's People's Liberation Army "Justice Mission 2025" joint exercise around Taiwan, where Taiwan’s Ministry of National Defense reported 27 live-fire rocket impacts in nearby waters, 71 PLA Air Force sorties with 35 crossing the Taiwan Strait median line, 17 PLA Navy vessels, and 15 China Coast Guard vessels by 15:00 local time, per an X post by @TaiwanMonitor citing the ministry’s press conference this morning.
