Albania's resistance after its government and army collapsed

Does prewar Albania provide a successful example of assuming that an opponent would not fight?

No, in this interpretation: the later resistance movement continued fighting and tied down troops even though the government and armed forces had collapsed.

The proposed counterexample is rejected because Albania's later resistance continued after the initial conquest. The resistance movement tied down occupation troops during World War II. The distinction is between the collapse of state forces and the willingness of people to keep fighting.
