Why was J. Robert Oppenheimer's security clearance revoked?

Oppenheimer's security clearance was revoked in 1954 by the U.S. Atomic Energy Commission due to suspicions raised during the McCarthy era. His previous associations with communist organizations, his opposition to thermonuclear bomb development, and concerns over his loyalty contributed to this decision, though no evidence of espionage was ever found.
