CIA Missions Can Last Multiple Years Undercover Before Mental Stress Becomes Dangerous

What was said

"It is rare to have a mission go longer than 3 years. That's so long. Yeah, that's why it's so rare because for someone to be in that level of stress for that long, it starts to have long-term mental effects on them. And as their mental capacity diminishes, the risk of the operation going upside down increases."

Bustamante disclosed that CIA undercover operations rarely exceed three years due to severe psychological toll on officers, with extended stress causing mental deterioration that jeopardizes mission security. He explained that maintaining a complete cover identity for years creates unsustainable pressure that increases operational risk. This revelation exposes the human limits of espionage work beyond the glamorized portrayals.
