Final answer:
Germany learned from its military defeat in World War I, leading to new tactics in World War II but ultimately facing defeat due to logistical challenges and enemy resistance.
Step-by-step explanation:
Germany learned a great deal from the military defeat it suffered in World War I. This defeat led to strategic changes, resulting in the development of new warfare tactics such as the use of fast-moving tanks and heavy bombers in World War II. While Germany had achieved a breakthrough in trench warfare at the end of World War I, they were ultimately pushed back, partly due to the American troops' involvement and the effective resistance by Belgium and France.
After World War I, the Treaty of Versailles significantly demilitarized Germany, stripping away its air force and navy and limiting its army. However, the lessons from the stalemate and attritional warfare on the Western Front, as well as the failure to knock France out of the war quickly, influenced German military strategy, and these lessons were applied in the initial stages of World War II with the invasion of Poland.
The early successes of this new approach, however, were eventually overshadowed by logistical challenges, underestimation of enemy resistance, and the harsh Russian winter during the invasion of the Soviet Union.
