How would a shorter war affect Britain?

How would this scenario affect Britain's economic position compared with the historical timeline?

A shorter war and fewer shipping losses would leave Britain with more of its commercial strength and a smaller financial burden.

Britain benefits from fewer merchant-ship losses and a less severe erosion of its pre-war commercial advantages. Lower debt burdens and less postwar disruption from the scale of American Liberty-ship production are also likely. Continued access to nearby Scandinavian resources further reduces the strain of long, vulnerable supply routes. These are contingent consequences of the scenario, not a claim that the British economy avoids every cost of war.
