Falsehood is a recognized and extremely useful weapon in warfare, and every country uses it quite deliberately to deceive its own people, to attract … - Arthur Ponsonby, 1st Baron Ponsonby of Shulbrede

War is fought in this fog of falsehood, a great deal of it undiscovered and accepted as truth. The fog arises from fear and is fed by panic. Any attempt to doubt or deny even the most fantastic story has to be condemned at once as unpatriotic, if not traitorous. This allows a free field for the rapid spread of lies. If they were only used to deceive the enemy in the game of war it would not be worth troubling about. But, as the purpose of most of them is to fan indignation and induce the flower of the country's youth to be ready to make the supreme sacrifice, it becomes a serious matter. Exposure, therefore, may be useful, even when the struggle is over, in order to show up the fraud, hypocrisy, and humbug on which all war rests, and the blatant and vulgar devices which have been used for so long to prevent the poor ignorant people from realizing the true meaning of war.

When the people of one country understand how the people in another country are duped, like themselves, in war-time, they will be more disposed to sympathize with them as victims than condemn them as criminal, because they will understand that their crime only consisted in obedience to the dictates of authority and acceptance of what their Government and Press represented to them as the truth.

War being established as a recognized institution to be resorted to when Governments quarrel, the people are more or less prepared. They quite willingly delude themselves in order to justify their own actions. They are anxious to find an excuse for displaying their patriotism, or they are disposed to seize the opportunity for the excitement and new life of adventure which war opens out to them. So there is a sort of national wink, everyone goes forward, and the individual, in his turn, takes up lying as a patriotic duty. In the low standard of morality which prevails in war-time, such a practice appears almost innocent.
