All this reminds me of the following quotes

"By way of deception thou shalt do war"
(unofficial translation of the) Mossad motto

"Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it"
Gospel according to the Apostle and Evangelist Saint John the Theologian

"You can fool some of the people all of the time, and all of the people some of the time, but you can not fool all of the people all of the time"
Abraham Lincoln
