Which agency is specifically responsible for maintaining the security of U.S. message traffic and intercepting, analyzing, and cryptanalyzing the messages of other states?
"Bureau of Intelligence and Research" would be the appropriate response.
Explanation:
The Bureau of analysis as well as Research keeps a database of Autonomous nations under such the region and perhaps a catalog of obligations or commitments and domains of exceptional independence.
Those other indexes include primary and secondary descriptions, two selected codes, as well as political or bureaucratic centers for communities as well as agencies.
