"A nation can survive its fools, even the ambitious, but it cannot survive treason from within. An enemy at the gates is less formidable, for he is known and carries his banner openly, but the traitor moves against those within the gate freely. The traitor speaks in accents familiar to his victims, and wears their face and their arguments. He rots the soul of a nation, he works secretly and unknown in the night to undermine the pillars of the city, he infects the body politic so that it can no longer resist. A murderer is less to fear." Marcus Tullius Cicero
