non-US is obsolete
Since the sarge release, packages that were formerly in the non-US part of the archive have been moved into the regular archive. If you have any lines referring to "non-us" in your /etc/apt/sources.list, you should remove them.
Cyber-warfare is a real thing. While government tends to be secretive about these things, they are indeed a big user of Linux and FOSS software. Government and DoD is right to be concerned that an agent of Iran or N Korea may attempt to contribute malicious code, in an effort to get it integrated with Linux based firmware, servers, phones, network infrastructure, and supercomputers.
