The X-Files, Season 6

Mulder:
(opening voiceover; about Cigarette Smoking Man and his father, Bill Mulder) Two men, young, idealistic - the fine product of a generation hardened by world war. Two fathers whose paths would converge in a new battle - an invisible war between a silent enemy and a sleeping giant on a scale to dwarf all historical conflicts. A 50-years war, its killing fields lying in wait for the inevitable global holocaust. Theirs was the dawn of Armageddon. And while the world was unaware, unwitting spectators to the hurly-burly of the decades-long struggle between heaven and earth there were those who prepared for the end; who measured the size and power of the enemy, and faced the choices: stand and fight, or bow to the will of a fearsome enemy. Or to surrender - to yield and collaborate. To save themselves and stay their enemy's hand. Men who believed that victory was the absence of defeat and survival the ultimate ideology... No matter what the sacrifice.
