"All warfare is based on deception. For years, the West's hypocrisy has made the world a battlefield. The corrupt talk while our brothers and sons spill their own blood. But deceit cuts both ways. The bigger the lie, the more likely people will believe it, and when a nation cries for vengeance, the lie spreads like a wildfire. The fire builds, devouring everything in its path. Our enemies believe that they alone dictate the course of history, but all it takes is the will of a single man." - Makarov in the introduction to Call of Duty: Modern Warfare 3, before the main menu appears. (This cutscene plays every time the game is started and can be skipped. It also plays when the player is idling in the main menu)
"Yuri, wake up. Zakhaev wouldn't want you to miss this. This deal will generate millions for our cause. Money can buy many things. Even power. The road to our future begins here, my friend." - Makarov to Yuri, just seconds before Zakhaev was shot.
"I know what you have done, Yuri. I know what you have told them. My friend. My ally. My betrayer. What happens here today, will change the world forever. Nothing can stop this. Not even you." - Makarov before shooting Yuri.
"I see...this is what we are dealing with, brothers. A stubborn old man, hopelessly out of step with the changing world.You too, will change. Are you listening?" - Makarov interrogating President Vorshevsky.
