Taiwan is building a smart plan to fend off a Chinese invasion, but its own politics, weak stockpiles, and shrinking military are undermining it — bad news for the island's survival odds.

• China's military dwarfs Taiwan's, so Taiwan bet everything on cheap, spread-out weapons — missiles, mines, drones, and civilian resistance — to make any invasion painfully costly.
• The Taiwan Strait itself is a huge barrier; crossing it would be the largest sea invasion in history, and Taiwan has packed its coast with anti-ship missiles to turn the water into a kill zone.
• Taiwan's China-friendly opposition slashed the defense budget and zeroed out new drone buying for 2026, even as Taiwan sits at under 10,000 combat drones versus millions for China.
• Behind the flashy weapons buys, Taiwan is short on ammo, rifles, fuel, and medical supplies, and still delivers draft notices by hand — full reserve call-up could take 60 to 90 days.
• A collapsing birth rate means eligible recruits will soon fall below 80,000, and trainers say most reservists get no real training at all.

Outlook: Japan, South Korea, and the Philippines may help, but unless Taiwan fixes its funding, stockpiles, and reserves fast, it stays dangerously unready whenever China decides to move.
