When war is declared, truth is the first casualty.
It is always desirable to tell the truth, but it is rarely necessary.
(Arthur James Balfour said)
There are only two people who can tell you the truth about yourself, an enemy who has lost his temper and a friend who loves you dearly.
The truth is incontrovertible. Malice may attack it and ignorance may deride it, but in the end, there it is.
(Winston Churchill said)
A lie that heals is better than a truth that hurts.
