The Unfinished Work: Lincoln's To Do List

In the Gettysburg Address, Lincoln said,

"The brave men, living and dead, who struggled here, have consecrated it, far above our poor power to add or detract. The world will little note, nor long remember what we say here, but it can never forget what they did here. It is for us the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced."

So for those who fought at Gettysburg, in Iraq and Afghanistan, for those who fought for human rights, for those who fought for social justice, what today should we count as that "unfinished work"?
