Should we continue to discuss the issue with respect to the German army ready for war in 1939? The bare facts and figures give a fairly clear picture, and they alone provide a comprehensive answer. But what would happen if France actually sent an army to the aid of Polish allies in the first half of September 1939? How might look like if the whole situation in Europe? After the defeat of Poland, Hitler could release all of its troops to the battle in the West. By the spring of 1940, he would win back the territory, captured by the French. And then - to get to the western borders of the Reich. Leave aside the damage that could cause a battle in the region west of the Rhine, as well as the industry in the area. Probably, the Nazi regime would fall in the autumn of 1939, but, even if Hitler was able to maintain its dominance in Germany, he probably would not be able to undertake large-scale offensive in 1940, as a result of which managed to capture the Netherlands, Belgium and France. Perhaps he could penetrate and Maas, but then would have been at risk to get bogged down in trench warfare. And what would it mean for the Western countries? They have won the most valuable thing for himself - namely, they would have won the time for re-equipment and would have found some new allies. In this situation, the German forces would probably be enough for the occupation of Norway. Balkan states are unlikely to feel the desire to communicate with Germany, which is still standing face to face with the undefeated enemy in the West. "Pact of Steel 'with Italy may also have remained idle. What would be the attitude of Russia in this scenario of events, it remains in question. It is no exaggeration if we say that their inaction in the West in 1939, the Allies allowed to miss a great chance to turn the fate of Europe in a different direction.
