Today, with the highly developed information technology, our weapons and equipment are constantly being updated, and the combat field is also showing a changing style with each passing day.Looking back at the two world wars in the 20th century, we will still find that some strategic and tactical principles in the two world wars still guide our war today. In terms of grand strategy, the lessons of Germany's two failures are most striking.Its problem is that once Germany is caught in a situation of being attacked by east and west, what awaits it is failure, and there is no hope of even a tie. Although the "Schlieffen Plan" is the best of all military plans, it deeply reflects how wrong German diplomacy is.If a country uses its military power rashly without the cooperation of clever diplomacy, it will plunge the country into a very risky gamble.Germany's failure illustrates: a country's diplomatic failures can completely negate its military advantages.

When serious mistakes in diplomacy make military operations an adventure, it is not necessarily impossible for Germany to win.However, when implementing the "Schlieffen Plan", Germany made the mistake of employing improper personnel and employed Moltke. Thus, we saw that when the German army entered France, the key right wing was not outflanked, and "let the right wing cover the strait" was not realized. Miracle".As a result, Germany fell into the dilemma of fighting on both sides of the east and west, thus losing the basis for victory. In the Second World War, Germany made the same diplomatic and military mistakes. The army fought in three directions, and finally failed under the attack of three sides.The combat history of the two world wars has proved a major feature of modern warfare with vivid examples: sea power has an absolute advantage over land power.

In World War II, although Germany had an absolute advantage on land, its opponents firmly controlled the command of the sea.Germany, surrounded by sea power, could neither defeat its land rival, the Soviet Union, nor could it pose a fatal threat to Britain and the United States, which controlled sea power.However, countries such as the United Kingdom and the United States can calmly mobilize war resources around the world to attack Germany from both the north and the south.The superiority of sea power over land power will remain unchanged in the future. Another lesson of World War II is that air superiority determines the outcome of a war.After the United States arrived on the European battlefield, it immediately launched a strategic bombing campaign against Germany. By destroying the heavy industrial facilities that Germany relied on during the war, it further destroyed the will of the German army to resist tenaciously.

On the Asian battlefield, the United States firmly controlled the sea and air supremacy, and then defeated the main force of the Japanese navy, which prevented the main force of the Japanese army in China and Southeast Asia from withdrawing to the mainland, and was paralyzed strategically. Battlefield air supremacy plays a decisive role in both strategic and tactical aspects of land and sea warfare.The Pacific battlefield of World War II showed that: due to the advent of aircraft and the opening up of the third dimensional space of war, sea dominance must be achieved through air dominance.

As far as the strategies of the two opposing blocs, the Allied Powers and the Axis Powers, the powerful sea power of the United Kingdom and the United States and the land power of the Soviet Union were successfully integrated, the Allies' "first Europe and then Asia" in the overall situation of the war seemed very organized. In contrast to the Axis powers, Germany’s land power and Japan’s sea power have never been able to cooperate. The reason is that Germany and Japan are limited in strength and are rising regional powers. Their strategic goals are limited by regions, and they fight independently without coordinated actions. .Moreover, the Soviet Union and China have a vast territory, and the huge space prevents Germany and Japan from joining forces.

The two world wars once again proved that science and technology are the source of revolution in the military field.The latest science and technology enable the invention of advanced weapons and equipment and arm the army, which in turn promotes the emergence of new arms and arms, changes in the formation and combat styles of the army, and the birth of new strategies and tactics. The two new technologies of internal combustion engine and radio communication gave birth to tank swarms, and aviation technology gave birth to the air force. The three major technologies led to the "air-ground coordination" of air strikes and ground tank swarms becoming the main land combat mode in World War II.

The experience of history is: Whoever perceives and implements a brand-new combat style first will be able to gain the initiative in war and defeat the backward opponent; Whoever has the advantage will win the final victory. From the perspective of the "middle period" of history, the two world wars were the power source for the gradual shift of the center of world power from Europe to the periphery and the Far East and the Pacific.The First World War resulted in the rapid attrition of the European powers and suspended the control and partition of the Far East colonies.After the Second World War, the European powers were severely weakened, and the Far East colonies got rid of the control of European countries and became independent one after another. With the status of independent sovereign states, a good environment for modernization transformation was created. 100 years ago, the Far East, which was regarded as a marginal zone in Europe, is about to become the center stage of the world.This centuries-old reversal of the center and the periphery in terms of geopolitical and economic geography is directly related to the two world wars.
