About war, they say, there is nothing new to besiege. It is as common to weaponize a classroom full of 10-year-olds, as it is to escort them to safety. It is the breaking of sanctions by black marketeers, and by equal turns, the secret liaisons of the brigadiers, that may dupe us into thinking the moat is filled with crocodiles. A man dancing and singing on the ramparts may be passing military secrets to the besiegers, or confident that the supplies within the castle walls will last a thousand years. Two men dancing and singing on the ramparts may be performing a Dirk Dance to train their troops in the art of hand-to-hand dagger combat, or in a much-maligned revival of Lerner and Loewe’s Camelot.
