   These _claims_, if true, are irrelevant to your claim as by then the   
   equivalence of rest energy and mass was already known.

   You appear to be confused about your own argument.  Now you are arguing,   
   *contrary* to what you argued before, that the known mass--energy   
   equivalence did play a role in the creation of the atomic bomb.  Make up   
   your mind.
