Retired US Rear Admiral Mark Montgomery warned in Taipei that China is learning Ukraine-style "adaptive warfare" faster than Taiwan is, which is bad news for Taiwan's defense unless it starts training with the US and Ukraine.

• Warfare has changed dramatically in three years, and only Ukraine and Russia are actually prepared for it; new drone tactics and tech appear in Ukraine every few months.
• China is sending people to Russia to study drone warfare, and Chinese parts are showing up in Russia's newest ballistic missiles, so China is "closer to combat-ready" than Taiwan.
• Taiwan's weapons buying system is not ready for this kind of war, and neither is America's.
• The biggest gap is that US and Taiwanese forces cannot easily work together: US ships can talk to Japanese or Korean ships instantly, but with Taiwan they would have to swap encryption keys by phone first.
• Montgomery wants regular joint drills, Taiwanese officers training in the US, and Taiwan's chip-based "non-red" supply chain expanded into drones, missiles, and microelectronics.

Outlook: Montgomery argues that making the US and Taiwan able to fight together should be a top priority, because it is the most credible way to deter China and avoid a war over the next 20 years.
