Could D-Day Happen Again? Normandy 1944 vs a Taiwan Strait Landing | Full Documentary

n June 1944, the largest seaborne invasion in history crossed a hundred miles of water and landed in Normandy. The Taiwan Strait is about the same width. So could a D-Day happen there today? This documentary walks through why the answer keeps coming back "no" — the phantom army of Operation Fortitude and the double agent Garbo; Rommel's Atlantic Wall; the Mulberry harbours towed across the Channel; the Black Water Channel and its two narrow weather windows; the night in 1949 when the tide stranded an invasion fleet at Guningtou; Operation Causeway, the American plan to invade Taiwan itself that was shelved in 1944; the missile age that erased the beachhead's first 72 hours; and the CSIS wargame that simulated the invasion 24 times — set in 2026.
