For Jerome Bonaparte, the war with the Russian Empire was merely a means to consolidate his own power and expand France's diplomatic space on the European Continent. He did not want to overly weaken the Russian Empire.
A weakened Russian Empire was only beneficial to Central Europe and Britain, and had no benefit for France, located in Western Europe. On the contrary, it would cause the German Region to focus all their efforts on guarding against France.
Even though the relations between the Austrian Empire and the French Empire seemed quite good now, once the Russian Empire weakened, conflicts between France and Austria in the German and Italian Regions would immediately erupt.
By that time, either he would lead the French Army to crush the states of the German Region, or the states of the German Region, led by Austria and Prussia, would brandish bayonets at his throat.
