We have 100's if not 1000's of nukes still baried out west in silo's, and our's should work(well when they were built and are tested weekly).
And you know we tested on Islands and in the weastern US for 30-40 years before we had what we wanted/needed.
Like when North Korea tested them under ground last year.
I realy dont see any more harm in that, then what we did for generations.
LOTS of "peacefull" Nations have simular weapons(nukes) at thier desposal but probly would never use them, if they even work at all from long term storage.
just my 7.5 cents
