Why was president Reagan unaware of the activities of his National Security Council?

President Reagan was often described as being disengaged from the day-to-day operations of his administration, relying heavily on his National Security Council (NSC) staff for information and decision-making. This delegation of authority, combined with a general preference for a hands-off approach, led to a lack of oversight. Additionally, the complexity and secrecy surrounding operations like Iran-Contra contributed to his unawareness, as key advisors may have withheld information or misled him about the extent of their activities.
