What would happen if Japan chose to continue fighting the Soviet Union in Nomenkan instead of attacking Pearl Harbor and attacking the Soviet Union in the north and south?
Let's start with the first one. If Germany had fought Britain wholeheartedly at that time, don't look at what advantage Germany had before fighting the Soviet Union in the British air war. But if this continues, Britain will certainly not be able to carry it. Because Britain has always been an island country, resources are basically replenished by sea. The wolf pack tactics caused great losses to Britain at first. Britain relies entirely on sea routes to supply the speed of building aircraft, which is basically not as fast as Germany relies almost entirely on European resources to build aircraft. If Hitler hadn't been eager to launch a blitzkrieg against the Soviet Union and transferred most of the main air force to the eastern front, Britain would have stayed a little longer at most. Sooner or later, we will lose the air superiority. Once the air supremacy is lost, even if the strength of the British navy greatly exceeds the estimate of the German navy, it will not be able to stop the German storm. Once the Germans landed in Britain, the British and French allied forces abandoned almost all the heavy equipment after the Dunkirk retreat. Facing the Germans in World War II at that time, it was basically scum.
Let's talk about the second one, if Japan had chosen to continue to entangle with the Soviet Union in Nomenkan (although it has been proved through two battles in Nomenkan that Japan's so-called elite Kwantung Army and chariot troops are all scum under the impact of the powerful Soviet air force and armored torrent). Even if we don't take the initiative to attack, we just harass from time to time, so that the Soviet Union can't easily mobilize the main force of the grassland army that was originally defended. Will the German attack on Moscow succeed?
Without "if", the sea lion project could not be realized, which involved too many problems and factors, which would have a great impact on the historical process before Germany attacked Britain. Simply put, the sea lion project itself was not realized by Hitler or Germany after the French campaign. In fact, neither the preparation of armed forces, the configuration and assembly of sailing ships, nor the discussion of amphibious combat mode can be produced out of thin air in just a few months. To achieve these conditions, it is bound to involve the German army 1936 or even a longer-term armament construction plan.
Under the condition of constant investment resources, the German army will be weakened in other aspects if it wants to meet these conditions. As a result, a series of German expansions from 1936 to 1939, including the French campaign, will be affected. And if you can't beat France quickly, then the Germans simply don't have the necessary conditions to attack the British Isles! Even if we take a step back, Germany did meet the conditions for implementing sea lions in a limited number of months, and it could launch an amphibious invasion of Britain before the tidal conditions deteriorated, but what was the result?
First of all, the British will not sit idly by while the Germans invade. At this time, the Royal Air Force and the Royal Navy are both in strength, and the German Air Force has only about 60% to 70% chance of winning the air superiority in the Straits. As for the sea, the German navy is facing the local fleet of the Royal Navy, which is several times more powerful. Not to mention the odds, even how to prevent British warships from breaking into the landing point in the strait is still worrying. What's more, Britain can also transfer H Fleet and Mediterranean Fleet from Gibraltar and Alexandria to help in times of crisis. After all, for Britain, the importance of native land is much higher than that of overseas colonies. It is no longer a problem that courage can solve to directly challenge the Royal British Fleet, which tied for the first place in the world at that time!
Of course, some people will think that the British army has just fled back to Dunkirk and even abandoned a lot of heavy equipment. As long as the Germans land, they basically win? However, at that time, there were not many allies sent by the British army to the European continent, and a considerable number of troops that had just completed mobilization could not be sent; Moreover, Germany's amphibious transportation capacity at that time was extremely limited. In the first 24 hours, it can only transport no more than 1 division to land, and after 72 hours.
The battle of Norway has fully exposed how unreliable the amphibious operations of the Germans were at that time. If it weren't for the arrival of the British and French allied forces, Norway's own defense force was seriously inadequate, and the Germans could not win at all. At that time, Britain was already on high alert for the German invasion, so a sudden attack was basically impossible, which would greatly increase the difficulty of the German invasion.
In fact, there is no "if" in this question, which is clear to future generations, but even so, German Lu Haijun still passed the buck and refused to start preparations, because they all knew how unreliable the Sea Lion Project was! That is, Goering promised to let the air force go first in order to win credit. Of course, the army and navy are happy to see someone jump into the fire pit!
Of course, history has no assumptions. History will always bring people only lessons and lessons! Oedipus, an ancient Greek tragic writer, famously said, "If God wants to destroy it, he must first make it crazy." Moustache and Tojo were both crazy at that time, so their demise was also a historical necessity!
