By December 1941, Germany was fighting the world's three largest industrial powers simultaneously. This was not forced by circumstance. It was a choice made by leadership that rejected everything German military tradition taught about the catastrophic cost of two-front wars. Every German officer studied how fighting Britain and Russia simultaneously destroyed Imperial Germany in World War I. Bismarck had warned that Germany's geographic position made avoiding two-front war the foundation of all strategy. Yet in June 1941, Hitler invaded the Soviet Union while Britain remained undefeated, voluntarily creating the exact strategic nightmare that German doctrine existed to prevent. This documentary examines why Hitler made this choice, which warnings from professional military officers were ignored, how the two-front commitment made decisive victory on either front impossible, and why the decision made Germany's eventual defeat mathematically certain regardless of tactical excellence. What You'll Learn: Why German strategic tradition identified two-front war as catastrophic. Hitler's rationale for invading the USSR while fighting Britain. The professional military warnings that were systematically ignored. How the two-front commitment created unsolvable resource allocation problems. Why Germany could not concentrate sufficient force on either front. The strategic paralysis that made both defense and offense impossible. How the decision to fight a two-front war guaranteed defeat before major battles were fought. This documentary is based on Wehrmacht strategic planning documents, postwar testimony from German generals including Keitel and Manstein, German military academy strategic doctrine, comparative industrial production statistics, and scholarly analysis from the U.S. Army War College and the German Militärgeschichtliches Forschungsamt.
