Final answer:
The advantages held by both sides in a war can cause the war to be much longer than expected. The American Civil War, for example, lasted longer than anticipated due to the unique advantages of the Union and the Confederacy. The Union had a larger population and better industrial capabilities, while the South had the advantage of defending familiar territory. These advantages led to a military stalemate and a prolonged war with no quick resolution.
Step-by-step explanation:
The advantages held by both sides in a war can cause the war to be much longer than expected. In the case of the American Civil War, both the Union and the Confederacy had certain advantages that prolonged the conflict. The North had a larger population, better industrial capabilities, and a more extensive railway network, which allowed them to mobilize more men and supplies. The South, on the other hand, had the advantage of defending familiar territory and shorter supply lines. These advantages led to a military stalemate and a prolonged war with no quick resolution in sight.
