like the supersonic Silkworm missiles - maybe the govt is going by the old saying "if you don't see it or hear it, it can't hurt you?"
with these new weapons, it can almost be true ... you won't feel a thing when you are in a billion particles.
China is modernizing and helping N. Korea. Both are selling weapons, incl. radiologicals, to Middle Eastern states (along with our good friends, the French) . . . We better get our heads out soon, or the 60s and 70s will seem like a picnic. :-(
