Why Nobody Invades Switzerland: The National Redoubt Strategy

Hitler drew up an invasion plan for Switzerland, then quietly shelved it. Why? Because Switzerland didn't just have an army—it had a mountain range wired to explode. In this briefing, we deconstruct the National Redoubt (Réduit national), the most ambitious defensive project in modern history. While the rest of Europe built walls, the Swiss turned the entire Alps into a self-sustaining machine of war. We explore the cold logic of General Henri Guisan, who realized that the Swiss plateau was indefensible and made a radical choice: retreat into the heart of the rock. This isn't just history. It's a masterclass in Geographic Deterrence. Geography of Doom reveals how a small, neutral nation used its terrain to become the only fortress in Europe that no one dared to touch.
