While Lincoln's Gettysburg address was a dedication to the Gettysburg memorial, it also contains a persuasive political argument about the justification for the Civil War. What is Lincoln's argument?

It’s hard not to love the poetry of the address, and there’s no reason to try. It’s also hard to look at such a revered speech with fresh eyes. But, other than honoring the fallen (including many Minnesotans who had fought heroically at that battle) and pledging to keep trying to win the Civil War, it’s hard to figure out the argument hidden within the poetry. It seems to be something like this:

Four score and seven equals 87 years, which leads to 1776, the year of the Declaration of Independence, which is what Lincoln refers to when he says that a new nation was “brought forth, upon this continent, conceived in liberty and dedicated to the proposition that all men are created equal.”

That “all men are created equal” was the first of the “self-evident” truths that Thomas Jefferson summarized in the second paragraph of the Declaration. Slavery, it seems obvious to us now, should have no place in a nation dedicated to that proposition. And yet it wasn’t obvious then. For 87 years after a new nation was conceived and dedicated to that proposition, slavery had continued, even after it had been abolished in much of the rest of the world.

The Civil War, Lincoln said, is a test of “whether that nation, or any nation so conceived and so dedicated, can long endure.” So perhaps that translates as: A nation dedicated to liberty and equality cannot indefinitely remain the last bastion of legalized human slavery.

Explanation:

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
