In what instance can classified information be shared with foreign governments?

Classified information can be shared with foreign governments through a formal agreement or treaty aligned with national interests. This means that there is a structured and legally binding framework governing the exchange of sensitive information, ensuring that both parties adhere to standards of confidentiality and mutual respect for the classification levels assigned to the information. Formal agreements typically outline the specifics of the information to be shared, the purpose of sharing, and the safeguarding measures required to protect it, thus minimizing risks associated with uncontrolled dissemination.

Other selections do not provide the necessary legal and procedural safeguards for sharing classified information. A verbal agreement lacks the binding authority and documentation necessary for ensuring compliance and accountability. The option suggesting that any government official can determine the need for sharing classified info lacks the checks and balances essential in managing sensitive data, as it risks circumventing established protocols. Lastly, sharing information during international conferences without restrictions disregards the need for proper classification handling and could expose sensitive data to unauthorized access.
