Following the original battle plan step by step and relying on the German military's strength to crush the Russian military bit by bit would have posed no problem at all. However, it would have taken a great deal of time. At the same time, German casualties would likely not have been low either.
If there had been no threat from other enemies, advancing in this manner would undoubtedly have been highly suitable. But the problem now was that the possibility of Germany's other powerful enemy, the United States, entering the war was growing ever greater. The United States was a world-class power second only to Germany in industrial and military strength. Without constraints from other nations, Germany possessed sufficient strength to defeat the United States. But Germany had already committed considerable forces to the Buru and Pacific theaters. This made it impossible for Germany to concentrate its strength against the United States. Therefore, to better counter the Americans' threat, Germany had to secure victory on the other battlefields as soon as possible.
The Pacific Theater was simply too far from the German homeland, and Germany's committed forces there were also very limited. Therefore, it was virtually impossible to end the war there quickly. Only on the Buru front did Germany have hope of swiftly ending the war. Even if it could not defeat Russia in a short time, it could at least seize the opportunity to deal Russia a crippling blow. That way, Germany would gradually be able to withdraw troops from the Russian front.
Once Buru had suffered catastrophic losses and its combat strength had greatly diminished, Germany would only need to leave behind a small number of troops on the Buru front. With the armies of its vassal states and protectorates as the main force, it would be
