NUCLEAR WHAT?.... PLEASE HAVE A RETHINK!

Every time , I read about Nuclear war, Nuclear weapon, Nuclear this, Nuclear that. I wonder what they want to destroy with all the nuclears. Definitely , it must not be humans.  But actually , they will use it to destroy both humans and properties. Do these warmongers know that humans do not live forever on earth? Why can't they allow people to live out their appointed time on earth instead of sending people to their early grave, and in such a horrible condition. Can the manufacturers and users of Nuclear weapons have a rethink of what they are doing. The highest a man will live on earth is a hundred and some tens of years. Why cut the life short with cruelty . Please have a rethink.
