Answer:
to argue that the impact of the war has not yet matched the impact of slavery.
Step-by-step explanation:
President Abraham Lincoln, for his second Inaugural speech for his second term as president, gave a touching speech where he emphasized on the need to lay importance on the effects of slavery for which all Americans, North as well as South, are implicit. And "this mighty scourge of war" is the divine punishment for the acts of discrimination against the blacks as acts of slavery. And even after all that has happened, the impact of war is nothing in comparison to what the slaves had to go through under the slavery system.
