1. 1. It should be 1939, forgetting to occupy Czechoslovakia or Austria first; 2. First of all, the air attack on Britain failed (Europe was not truly unified and the attack was contained); Then, Germany's strength was reversed in the Battle of Stalingrad (the most important turning point); Finally, the German navy, due to the birth of sonar technology, the advantage of German sea wolf tactics no longer exists; The air attack on Britain was changed to an air attack on London (London bombing) because it did not insist on destroying the opponent's radar system. Britain can breathe, build more radars and train pilots. Finally, the resistance of Germany's air strikes against Britain is getting bigger and bigger, and finally the losses are heavy; Secondly, the reason for turning to bombing London was that the British had a bad idea. Although Britain almost collapsed at that time, it finally decided to let its remaining air force bomb Berlin, which made Hitler angry (once said that Berlin could never be attacked by the enemy) and turned to air strike London (London withstood the air strike). The main reason is that Europe cannot be unified without conquering the English Channel. Secondly, Europeans have always had conflicts with the Soviets. In fact, I think the main reason is that the Soviet Union has more resources, and at that time, the Germans were good at dodging, attached importance to the air force and the army, and of course included some power struggles. 4. The main battlefield, Britain and the Soviet Union; Secondly, the United States (I don't want to say much, selling equipment, rushing to the battlefield in Europe, mending a knife, etc., there are many volunteers behind, and there are oppressed people).

2. 1. The outbreak of the European battlefield is equivalent to the outbreak of World War II and the London bombing. 2. Someone said; 3. I have already said it; 4. Britain, Germany

3. Personally, I think that the Asian battlefield officially started when Japan entered Korea, and I can't remember the time; Of course, the army is in China, cleaning up garbage in major battles; 3. Of course, Japan also needs to plunder resources. Not only China, but also various islands, including Myanmar and India, are strategic places such as important passes, ports, resource areas and springboard. Mainly strategic expansion. 4. In China, the United States and Japan, the Japanese aircraft carrier was destroyed, and the Japanese army was destroyed. It returned to the mainland to defend itself. The atomic bombs exploded in Hiroshima and Nagasaki, and the game was over.

4. 1 1.94438+0 At the end of the year, Japan attacked Pearl Harbor, forcing the United States to declare war, and the allies had powerful allies. Soon China officially declared war on Japan, firmly containing most Japanese troops and paying a huge price for the victory of World War II; 2. The Pacific War, the turning point of Midway Island, followed by the island jumping plan to control major bases such as Guam; 3. It is simply that the Japanese are so self-righteous that the navy has no rivals (but the Japanese navy was indeed one of the best in the world at that time), and as a result, they blindly challenged the US Pacific Fleet and committed suicide. 4. USA and Japan

5. 1. Unknown event, Rommel 194 1 year blitzkrieg; 2. Rommel escaped, the battle of Montgomery El Alamein was successful, and then North Africa was recaptured. The fundamental purpose is to open up the third war zone, not to occupy Africa, but to plunder Africa's resources, that is, it is not the main battlefield, mainly to seize more chips and resources. 4. Britain and the United States against Germany (in fact, France also participated, and the position is to participate, without much comment).
