Similarities and differences between German operations on the Western Front in World War I and World

The Schlieffen Plan of Germany during World War I required soldiers to fight positional warfare with France, with the main purpose of destroying the French living forces and forcing France to surrender.

During World War II, Manstein's plan was to take advantage of the concentration of tanks and fight more and less in the Ardennes Forest in order to occupy the Maginot Line from behind.

It was Germany that declared war on the United States after the United States declared war on Japan at Pearl Harbor time, and the United States declared war on Germany. The time is 12/11/41. The earliest battle should have been the strategic bombing of Germany on August 17, 1942 with the participation of the U.S. Eighth Air Force.

Because until Operation Torch, the only anti-fascist fronts in Europe were the Soviet Union in the east, North Africa in the south, and sporadic air battles over Britain in the northwest. The U.S. Army was not involved.

In addition, during the Battle of the Atlantic, in July 1941, American troops landed in Iceland and took over the British army to defend the island. Subsequently, the United States took on the task of escorting the convoy west of Iceland. The move marked the gradual involvement of the United States in the war.

On 11 September, Roosevelt announced the principle of US escort in the Atlantic: The United States will implement a policy of "striking at sight" against German ships in the Atlantic without waiting for the other side to attack first, which is actually the United States' undeclared war against Germany. It is estimated that there will also be a battle between the US Navy and Nazi submarines.

However, the specific details are hard to find, and the time is needless to say.

2. Smoke and drink alcohol, and wear loose and ventilated clothes.

Summing up the common reasons, I think there are the following points: (1) Germany is a rising capitalist monopoly country, but because the world market and raw material land are basically carved up by the old powers, it has to expand its class interests by expanding arms warfare (2) Germany itself has embarked on the capitalist road by relying on top-down dynastic wars, and has retained a large number of militaristic traditions, As a result, the landlord class and the military aristocracy colluded together (3) the Germanic nation had a natural heroic plot, and under the instigation of nationalism, it was very easy to be used by the ruling class (4) it was influenced by geostrategy, suppressed by traditional countries, and had a strong sense of revenge (5) its own industrial economic foundation was relatively strong, and its wartime economy could withstand a certain period of attrition (6) changes in the international environment, and the power of pro-German groups with common interests became increasingly strong and moved towards international union, However, the internal contradictions of the group are complex and cannot form a whole in the short term.

After Germany completed the second industrial revolution, the country's economic and military strength was greatly improved, and it rapidly grew into an industrial power, but the colonies at that time had been carved up, Germany was not satisfied, and because Britain did not seize the second industrial revolution, the national strength was weakened, Germany asked to re-divide the colonies on all continents of the world, but Britain and France and other countries did not agree, so the contradictions intensified and escalated, and finally the fuse exploded in World War I. Germany was defeated. After the signing of the Treaty of Versailles, Germany could not be fortified within 40 kilometers of the Rhine and was not allowed to have an air force, and later Hitler's party was established, which preached national hatred everywhere, demanded the overthrow of the Treaty of Versailles, expanded its armaments, and raided Poland, and World War II broke out.
