Oddly enough, it was the Third Reich who declared war on the U.S. Until then, we had only been suppling Britain and defending the shipping lanes we were using to do so. The U.S. would most likely not have entered the war in Europe if it hadn't been threatened by the declaration. However, Just War Theory concerns itself with when war may be ethically justified. Consequentialists, on the other hand, would have had to predict whether or not American involvement would end in a better result, and between British aerial and naval actions, widespread resistance movements in Europe, and the overwhelming numbers of the Soviet troops, along with the barely-suspected, subsequent Cold War, which began over disputes on how the conquered Axis countries would be managed by the Allies, that would not have been an easy task.Was it right for the US to join the allies in resistance?
