"["I Believe" trailer] My name is Sam Fisher. I'm a soldier. I'm not much of a philosopher, but if you want to know what I believe, I'll tell you. I believe the greatest threats to our freedom actually start small. They begin as random events that most people don't even notice. But they grow. They multiply. They start chain reactions that threaten the entire world. Some people call that "fate". I call it "Chaos Theory". But, believing in Chaos Theory doesn't mean you have to surrender to it. That's where I come in. I find those threats before they get out of hand, and I eliminate them. Quickly, quietly, relentlessly. I take the lives of a few to protect the lives of many. I commit acts of war to preserve the greater peace. I take no joy in killing, but make no mistake; I'll do what needs to be done. Because it's my job. It's my duty. My name is Sam Fisher, and I am a Splinter Cell."
