What is the U.S. equivalent classification level for a foreign government's classification of "Restricted"?

The U.S. equivalent classification level for a foreign government's classification of "Restricted" corresponds to "Confidential." This classification level is used for information that, if disclosed, could cause damage to national security. In many foreign classification systems, the term "Restricted" often indicates a similar level of potential risk, where there is a need to keep information secure but not at the highest security level.

When comparing classification levels, "Confidential" aligns with the idea of protecting not only state secrets but also sensitive information that requires governmental control. This makes it critical to ensure that those who have access are properly vetted and that dissemination is controlled.

The other options suggest higher classifications that are used for more sensitive information requiring stricter controls, or they indicate no classification at all, which would not be suitable for the protection built into "Restricted." Thus, "Confidential - Modified Handling" is the most appropriate U.S. classification that matches the nature of "Restricted" from a foreign jurisdiction.
