for us old farts, that as kids grew up with the blockade of the Suez Canal, Cuban Missile Crisis, Conelrad marked radios, participated in "duck and cover" drills at school...later spent a good portion of military service targeted against Cold War targets...whose friends handled SADM (backpackable) and MADM (vehicle portable) atomic munitions...it would seem very likely that a few of those old Cold War relics, or more likely purchased from some rogue former Block nation might still be floating around.... we know there are individuals willing to use them
