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 be a worse case.
You may have to fight when there is no hope of victory,
because it is better to perish than to live as slaves."
Churchill
