HELP I NEED answer NOW What two reasons does Lincoln give for launching military action against the South?

to honor the common soldiers and sailors who have not abandoned their posts
to teach Americans that change can only come peacefully, through elections, not through war
to guarantee that every state continues to have a republican form of government, as promised by the Constitution
to preserve a government dedicated to giving each citizen a fair chance
to take revenge on the treacherous officers who abandoned their flag
