US allies in Asia wary as Trump moves military assets for Iran war

What the report says

US allies in Asia are watching closely as Washington shifts some military resources to the Middle East for the prolonged US-Israel war on Iran, raising questions about how much capacity remains to deter China. Al Jazeera reported on Aug. 21, 2026, that the United States moved its last aircraft carrier in the Asia-Pacific, the USS George Washington, from Japan to the Middle East to replace the USS Abraham Lincoln after an extended deployment.

The carrier move follows earlier reports that the US transferred parts of its THAAD missile-defense system from South Korea and drew down missile and munitions stockpiles to sustain the war effort. Analysts quoted by Al Jazeera said these steps may weaken US operational flexibility and send a signal that could encourage Beijing to test regional responses. Chinese coastguard activity near waters east of Taiwan has also increased since June, according to the article, adding to concern in Japan, the Philippines and Taiwan.

At the same time, the report noted that most US forces remain in the region, including roughly 375,000 military and civilian personnel assigned to US Pacific Command. Several experts said the carrier redeployment looks more like a short-term adjustment than a lasting retreat, especially as the Trump administration continues to press allies to shoulder more of their own defense.

The article said South Korea, Japan, Taiwan and the Philippines have been responding by increasing defense spending and deepening security cooperation with one another. That broader shift matters because it suggests regional states are preparing for a future with less direct US support, even if Washington’s military focus eventually returns to Asia.
