Taiwan and other US allies in Asia are facing long delays on missile deliveries, a bad sign for the region's defenses as China builds up pressure.

• Taiwan expects "serious delays" on Patriot PAC-3 interceptors because the Pentagon burned through its stock in the Middle East.
• Japan has been warned that Tomahawk cruise missiles and other gear could arrive up to two years late.
• Nearly $30 billion in weapons already approved for Taiwan still have not been delivered.
• More than 30 warships meant for the Pacific were moved to the Middle East, along with an aircraft carrier based in Japan, and a joint landing drill with South Korea was scrapped.
• The US is estimated to have only around 1,000 Patriot and THAAD interceptors left, against China's 3,000-plus ballistic missiles.

Outlook: Washington will focus on refilling its own and Gulf allies' stockpiles first, so Asian deliveries are likely to slip further while Trump courts Xi and Kim.
