What is the primary criterion for screening individuals out of the nuclear weapons program?

The primary criterion for screening individuals out of the nuclear weapons program is based on emotional disorders and character deficits. This criterion is essential because individuals working in such high-stakes environments must demonstrate a high level of psychological stability and maturity. The responsibilities associated with nuclear weapons require personnel to be reliable, level-headed, and able to manage stress and pressure effectively. Emotional disorders can impair judgment, decision-making, and the ability to function cohesively within a team, all of which are critical for maintaining safety and security in the nuclear weapons program.

In contrast, while factors such as incapability to perform under stress, inability to follow instructions, and physical training inadequacies are important in assessing overall suitability for various military roles, they do not encompass the psychological aspects necessary for handling nuclear weapons. Emotional stability is paramount, prioritizing mental health to ensure that individuals can perform their duties without risking the security of such sensitive operations.
