Final answer:
NATO RESTRICTED information is safeguarded similarly to the U.S. Department of Defense's Confidential information, with access control to prevent unauthorized disclosure. The Supreme Court permits the press to print classified material provided it does not endanger troops or covert operatives.
Step-by-step explanation:
NATO RESTRICTED information should be safeguarded in a similar manner to how the Department of Defense protects its information marked as Confidential. This level of classification requires measures to ensure that access is limited to individuals with the appropriate clearance and need to know, to prevent unauthorized disclosure that could cause damage to national security.
Regarding the Supreme Court's stance on the press printing classified material, the Court determined that the right of the press to print such material is partial, and the press may print classified material only if it does not compromise troops or covert operatives. This balances the freedom of the press with the necessity to protect national security and the safety of individuals involved in sensitive operations.
