This speech reminds me of the MacArthur quote, "It is fatal to enter any war with out the will to win it."
This here is one hell of a display of will:
"There is one great thing that you men will all be able to say after this war is over and you are home once again. You may be thankful that twenty years from now when you are sitting by the fireplace with your grandson on your knee and he asks you what you did in the great World War II, you WON'T have to cough, shift him to the other knee and say, "Well, your Granddaddy shoveled shit in Louisiana." No, Sir, you can look him straight in the eye and say, "Son, your Granddaddy rode with the Great Third Army,""
Fight for the movement for indefinite life extension so that in the future you may be able to say something similar.
