In the summer of 2022, just months after Russia invaded Ukraine, Taiwan’s president gathered senior officials from her ruling party in downtown Taipei. On the agenda: How was Ukraine, in its war with Russia, successfully offsetting the advantages of a much more powerful foe?

President Tsai Ing-wen was given an internal 77-page briefing report via PowerPoint. It had a clear answer: drones.

"Since the war began, Ukraine, which was previously considered as lacking air supremacy, cleverly used drones to create its own partial air supremacy,” the presentation stated.
