Going back to Clausewitz, war is a continuation of politics through other means. Moreover, victory is achieved by using force to compel one's opponent to carry out one's will.

> intact and combat capable

On its own, this claim is likely true. Nevertheless, this does not mean one's opponent is going to carry out one's will. Hence, one cannot declare victory. It follows that anything short of achieving one's goal is a loss. A loss doesn't have to be complete and utter destruction. It's fair to say that Argentina did not achieve its strategic objectives during the Falklands War, no?

> Losing is what happened to Germany after both World Wars.

Yes, but Germany is not as good of an example in this case as Japan during WWII. Japan would have likely accepted something short of unconditional surrender much sooner than August 1945, but the U.S. insisted on unconditional surrender. As such, the U.S. did not win until Japan agreed to unconditional surrender.
