Poland’s congenital deficiencies + the Soviet Union stabbed in the back, this is actually a crime of non-war (of course, we will not talk about the previous Soviet Union’s attempt to help Czechoslovakia through Daulan, but was rejected by Dabobo). Let’s look specifically at the situation in France and the Soviet Union. [French Campaign] France: 1. Appeasement is the consensus of French public opinion. The shadow of World War I caused the people themselves to be unwilling to fight. The French surrender is the right answer for the people. After all, from a racial perspective, Hitler would not attack the French. Extinction: That’s why there is a joke: “No matter what shortcomings the Petain government has, it can do things related to surrender, and it can do it vigorously.” 2. The military’s tactical thinking stayed during the First World War, and basically hoped after the declaration of war on Germany. Relying on the Maginot line of defense once and for all, there was no effective war mobilization at all, and the management of armaments resources was also messed up (for example, after the surrender, there were more fighter aircraft reserves than war). That’s why there is a well-known “false war”; 3. Lack of strategic depth, the German army If conditions permit the rapid occupation of important cities such as Paris through a blitzkrieg, France can only surrender; 4. Britain and France themselves have not reached an absolute tacit agreement. The biggest casualties of the French Navy in World War II was the British attack on the French military port. The German side: 1. Boldly chose the Ardennes Forest as a breakthrough point, bypassing the French heavy fortress in one fell swoop, and caught France by surprise; 2. Hitler had previously annexed Austria, dismembered Czechoslovakia, and blitzed Poland to accumulate high popularity, allowing him to rank high. The people’s decisive decision to go to war (and the failure of his assassination), the mobilization effect of the whole army was stronger than that of France; 3. The Versailles Treaty caused many years of humiliation to Germany, and the people did not have too strong anti-war sentiment (after France surrendered, even Germany) Some people who opposed Hitler were so excited that they burst into tears and chanted long live). [Soviet Campaign] The Soviet Union: 1. Unexpected depth of the country + unlimited population + sparse infrastructure (causing the German army to advance quickly) + winter nuclear weapons; 2. Hitler’s ideological hostility to the Soviet Union and the Slavic peoples, such as massacres , Shooting all Soviet political commissars, etc., resulting in only truthful propaganda, enough to give the Soviet army and civilians more reason to resist to the end, lack of room for compromise; 3. The Soviet Union decisively transferred arms manufacturing plants, and quickly restored production capacity, while gaining Material support from the United Kingdom and the United States; 4. Stalin quickly cheered up after the initial strike, and equipped the Red Army with commanders such as Zhukov and God of War, and the Red Army formed a cohesive force. On the German side: 1. Encountered with the interference of the Soviet-Finnish war, insufficient judgment on the combat effectiveness of the Soviet army, unable to achieve the strategic goals as planned; 2. Failure to force the British to surrender before launching Barbarossa, and was in a two-sided combat situation for a long time; 3. Small country resources The population has an upper limit, the front line is stretched + the battle situation is stalemate, it is easy to care about one and the other, one step is wrong; 4. Also because of the shortage of labor, a large number of foreign labor and prisoners of war can only be used, and the production efficiency is not guaranteed. 5. Italian pig teammates rashly invaded Greece, affecting Germany’s original plan.
