You have to run risks. There are no certainties in war. There is a precipice on either side of you - a precipice of caution and a precipice of over-daring.

It is no use dealing with illusions and make-believes. We must look at the facts. The world ... is too dangerous for anyone to be able to afford to nurse illusions. We must look at realities.
