Do some research. It would take more than a Scud to go high enough for an EMP attack. Yes, China, Russia, and maybe Norks have ICBM's. We would see them upon launch and figure the trajectory. No, they don't have the capability as yet to take out are satellites. Plus, simple Aegis class cruisers can see them upon launch. Then you have redundant radar at so many Air Force bases and SAC. Please, no one is going to attack us with nukes knowing America has already nuked Japan, twice.
FYI: Isotope identification devices are usually quite compact and very sensitive radiation isotope identification device, which enables detection, localization and identification of radioactive and nuclear materials. Isotope types are detected by their neutron and gamma radiation along with their amplitude gamma spectra.
We now have such devices in every port of entry. You're behind the curve. I'm not whistling past the graveyard. I will say again, once the isotopes are identified from their origin, Tridents will obliterate with nukes and/or massive cruise missiles any nation or terrorist group that nukes us. The world knows they are out there and that's why we haven't been nuked. Sleep in peace, Sir. The Silent Service is out there on patrol everywhere.
You’re wrong, but I really don’t care. Nice talking to you.
