Yea, what Churchill said

If you will not fight for right when you can easily win without blood shed; if you will not fight when your victory is sure and not too costly; you may come to the moment when you will have to fight with all the odds against you and only a precarious chance of survival. There may even be a worse case. You may have to fight when there is no hope of victory . . .

Winston Churchill
(1874-1965, English statesman, orator, author, and defender of Britain)
