What action should be taken if classified information is set for declassification but still poses a threat to national security?

The appropriate action when classified information is scheduled for declassification but still poses a threat to national security is to extend the information's duration of classification. This option ensures that sensitive information remains protected until it can be assuredly verified as no longer posing a risk. Classification decisions are made based on the potential harm that could result from unauthorized disclosure, and if there is an ongoing threat, extending the classification helps maintain national security interests.

Continuing to classify the information allows authorities to assess the potential risks comprehensively and determine when, if ever, it can be safely declassified. This approach aligns with the principles of safeguarding national security while adhering to established protocols for the handling of sensitive information.
