Which factor is crucial in determining what information can be disclosed?

The sensitivity of the information in question is a critical factor in determining what can be disclosed because it directly relates to the potential impact that disclosure could have on national security, operational effectiveness, or diplomatic relationships. Sensitive information, particularly that related to military operations, capabilities, or intelligence, requires a careful evaluation before it can be shared with foreign entities. This evaluation ensures that the potential risks associated with disclosing such information are thoroughly assessed and mitigated.

In the context of foreign disclosure, evaluating sensitivity involves understanding different classification levels and the specific legal or policy regulations governing the handling of that information. The sensitivity assessment helps FDOs determine whether disclosures are permissible, what additional safeguards may be required, and to whom the information can be shared without exposing the U.S. government to unnecessary risk. This process is vital for maintaining operational security and protecting vital interests.
