War is merely the continuation of policy by other means.
-- Karl von Clausewitz
It is well that war is so terrible - otherwise we would grow too fond of it.
-- Gen. Robert E. Lee (1862)
Never, never, never believe any war will be smooth and easy, or that anyone who embarks on the strange voyage can measure the tides and hurricanes he will encounter. The statesman who yields to war fever must realize that once the signal is given, he is no longer the master of policy but the slave of unforeseeable and uncontrollable events.
-- Sir Winston Churchill
