Step-by-step explanation:
In the given context, "the burdens of occupation it must lose" means that Germany would be unable to sustain its occupation of the conquered territories in Europe and maintain a continuing land war while trying to win control of the seas. The phrase suggests that Germany would be overstretched in its military operations and occupation duties, leading to a weakening of its position in both areas. The burden of occupation refers to the costs and difficulties associated with managing and controlling the occupied territories, including managing resistance, providing resources, and ensuring compliance. The phrase implies that Germany cannot afford to continue occupying the conquered territories and must abandon them to focus on winning control of the seas if it wants to achieve its ultimate goal of dominating the world.
