All's fair in love and war again

 

 Against such lewdsters, and their lechery,

Those that betray them do no treachery.     

 

-- William Shakespeare, The Merry Wives of Windsor, Act 5, Scene 3

All's fair in love and war

 

 

 

 

A just war may be prosecuted after a very unjust manner; by perfidious breaches of our word, by inhuman cruelties, and by assassinations.

-- Francis Atterbury 1662-1732
