There's a good possibility that Saddam was traced by Tempest sensing, airborne or mundane. The technology is far more sensitive than a decade ago. And with a lot of snooping technology kept obscure by tales of HUMINT, finks, lost laptops and black bag jobs. For less sensitive compromising emanations, BETA, among others, makes portable Tempest units, desktop and room-sized, the devices export-restricted as if munitions. There's a patent on a booth-like Tempest device into which the user climbs, with protection provided for connections, but whether it was ever built is unknown. A slew of firms make Tempest products which can be examined for what shielding works sufficiently well to be placed on NSA's more or less trustworthy Tempest products list: Beyond commercial-grade, NSA is reportedly able to read faint emanations from all known Tempest protection, thanks in part to reviewing products and international sharing among spooks. Those leaked from fiber are now a piece of cake, and not by tapping the glass a la the RU submarine cable escapade and the derring-do of USS Jimmy Carter custom-rigged to hack transoceanic fiber. Tempest snooping at the atomic level is feasible, thanks to physicists who walk among the electrons with supercomputers. As ever, what you don't know is what kills you, and if you are not currently doing research or working on NDA stuff, you're toast. Protecting against the known is what keeps the orchestrated leak industry thriving. Be sure to submit bright inventions to the authorities to get contracts for funding dark ones that work against the grain, then you'll get really swell contracts or offed. Ex-NSA staff are rolling in clover selling commercialized versions of security technology that NSA freely accesses. Reminds of the Brits selling to gullible govs impregnable Enigma machines after WW2.
