I just played my first game of BSG (solo using the official fully cooperative rules). I've got the german edition so my card names might be a bit off...
The card "Inspirational Speech" says something like:
Action: Roll dice. If you roll 6 or higher you get +1 Morale and this card is put out of play. Otherwise it has no effect and is discarded.
Now apart from gaining the 1 Morale, what is the difference of what happens with the card?
